Opis:
Prognozy zmian stosunków wodnych w rejonie likwidowanych kopalń Tarnobrzeskiego Zagłębia Siarkowego, wykonane na podstawie wyników modelu hydrogeologicznego, wskazują na możliwość ujawnienia się negatywnych zmian w środowisku wodno-gruntowym po wyłączeniu istniejących systemów odwadniających. W obrębie kopalni "Jeziorko" i w otoczeniu kopalni "Piaseczno" uregulowanie stosunków wodnych ma podstawowe znaczenie dla dalszego kierunku zagospodarowania terenów pogórniczych. Artykuł dokumentuje wpływ odtworzonego zwierciadła na produktywność gleb, stopień uszkodzenia i główne zagrożenia, których usunięcie wymagać będzie wykonania specjalistycznych melioracji szczegółowych.
The water conditions prognosis within the area of mines put to closure of Tarnobrzeg Sulphur Basin, elaborated on the basis of hydrogeological model results, show the possibility of occurrence the negative changes in ground-water environment, after eliminating the existing drainage systems. Within the surroundings of "Jeziorko" and "Piaseczno" mines, the water conditions engineering is of basie importance, for further direction of post-mining land development. The paper presents the evidence of the influence of reconstructed ground-water level over the soil productiveness, the size of damages and main threats removal of which needs to carry out special detailed land melioration.

Opis:
This is the first academic study of this type pertaining to the history of tourist traffic in the area of the Bochnia Salt Mine. In contrast to the Wieliczka Salt Mine, no general academic or popular science studies have been prepared with respect to this issue to date. Prior works devoted to the Bochnia Salt Mine did not deal with this issue. The objective of this article is an attempt at describing, throughout the history of the Bochnia Salt Mine, the gradual process of emergence and development of tourist traffic. The author of the work makes use of the existing manuscripts and printed sources, along with academic studies devoted directly or indirectly to the subject matter pertaining to the content of the article. Interviews conducted with the present and retired employees of the Bochnia Salt Mine also turned out to be helpful, both directors and traffic supervision employees, as well as persons directly involved in the tourist traffic servicing. Thanks to this, the gaps existing in the source materials and academic or popular science studies pertaining to the subject matter of the study were supplemented or filled. The history of tourist traffic described in the article was closely related to the history of the Bochnia Salt Mine. The reader is going to find out that this process was not easy, whereas its history is replete with obstacles and threats during various stages of development, including a complete disappearance of tourist activity, which was finally reinstated and which has been pursued to date. Therefore, the issue deserves a detailed study. In medieval sources, it is possible to find traces of princes’ and kings’ (and their officials’) stays in the mine. Such visits were purely official. Their objective was direct or indirect control over all aspects of operation of the subordinate enterprise. Visits of representatives of commerce and handicraft in the Bochnia Salt Mine, whose enterprises were closely and durably related to the current operation of the mine, had a more “economic” character The situation was similar with holders of permits and privileges from the group of contemporary wealthy people, both clerics and secular. The ongoing necessity of taking care of their economic interest was the most important for this group. Sources between the 16th and the 18th century offer new data. New categories of guests supplemented the above list of visitors in the Bochnia Salt Mine. The first one includes various travellers who, in their accounts or descriptions, offer the first experiences accompanying visits in the underground section of the mine. Another category are poets. Their works, preserved in the modern times, have a similar character, yet by their nature they are more filled with emotions. Therefore, all these authors were, in a certain way, “pioneers” – the first tourists in the modern sense of the word. The third category includes representatives of science, testifying to the growing interest in the Bochnia Salt Mine from a scientific perspective. They also form a part of the previously described group of travellers, who were testing their talents in the new area. These were predominantly people connected to the Bochnia Salt Mine who implemented their ideas, plans and intentions for its benefit. There was also yet another special category – the so-called “unwanted guests.” This group includes both “locals” and “foreigners”, whose activities had an adverse impact on the situation of the Bochnia Salt Mine. At the end of the 18th century, a certain fundamental change occurred in the above-described group of “guests” at the Bochnia Salt Mine. The owner of the mine changed – the Polish king was replaced by the Austrian emperor and royal officials were substituted by the imperial bureaucratic apparatus. Simultaneous abolishment of former permits and privileges resulted in absence of visits of clerics and lay people. What is more, the former system of connections of the mine with trade and municipal handicraft also ceased to exist. Representatives of such professions disappeared almost completely from the area of the Bochnia Salt Mine. The 19th century, especially its second half, brought development of initially disorganised tourist traffic in the form of individual and collective groups. Visits in the mine, hitherto a privilege reserved for the chosen few, suddenly became a very fashionable pastime for a broader group of people. This situation was intensified by development of communication and dissemination of press information, as well as popularity of local sightseeing associations. Such groups included local people, as well as guests from other countries, officials, teachers, clerics, military men, young people and children. The number of descriptions and travellers’ accounts, resulting from visits in the underground pits of the Bochnia Salt Mine, also soared. The Bochnia Salt Mine has become a more attractive place for the conduct of scientific studies by outstanding researchers and specialists from various areas of knowledge. The Bochnia Salt Mine was also a venue for didactic activities for the future practitioners of science, who pursued classes, internships and professional practice here. However, the described century and the beginning of the 20th century were not free from negative activities and decisions of the group known from earlier centuries as the “unwanted guests.” The inter-war period was a time of constant struggle with the governmental plans of liquidation of the Bochnia Salt Mine. In spite of the difficult situation, the unorganised tourist traffic of numerous groups and individuals (from the country and abroad) continued to flourish in the mine. The mine was also visited by scientists and young graduates who were acquiring the necessary knowledge and professional skills. What is more, middle school pupils and college students followed the example of their senior friends and attended special classes in the mine and visited it as part of activities of school sightseeing groups. It is also worth remembering that the outbreak of WWII halted the plans of establishing a sanatorium at the Bochnia Salt Mine. The period of Nazi occupation brought an end to popular visits in the Bochnia Salt Mine. At this time, the mine was only open for German people – ordinary citizens and military men. However, traces of stay of Polish people in the mine from this period have also been preserved – obviously, such visits were only possible upon the approval of the occupation authorities. Throughout the communist period, the idea of making the Bochnia Salt Mine available for tourists was not popular and it resurfaced only in the form of sporadic initiatives. In the 1950s, a visit in the mine formed a part of subsequent historical anniversaries celebrated in the city and the local saltworks. Similar initiatives, even though planned, were not implemented in the 1960s - they were going to form a part of the celebrations of the 1,000th anniversary of the Polish state. Nevertheless, plans pertaining to the visits in the Bochnia Salt Mine in the 1970s were successful – they were included in the extensive programme of the “Days of Bochnia” inaugurated at that time. The last activity in the described period took place in the 1980s, when sightseeing in the mine was included in the celebrations of another historical anniversary of the city. The 1980s were also a time of clear increased interest in the Bochnia Salt Mine as a historical facility. Inclusion of the most valuable pits and surface development of the mine in the list of national monuments definitely contributed to it. Simultaneously, next to the gradual process of limiting the industrial operation of the mine, former plans of establishing a sanatorium were brought back. This very difficult process of building a tourist and spa centre commenced at that time was halted by the political transformations of 1989. After 1990, it was continued for a long time until the middle of the 1990s. The author of the work adopted the year 1995 as the end for the study; it constitutes the opening of a completely new chapter in the history of the Bochnia Salt Mine. The unorganised tourist traffic was provided with durable legal and organisational framework in the form of a newly-established entity: Uzdrowisko Kopalnia Soli Bochnia Sp. z o.o. Between 1995 and 2014, the company has been servicing numerous groups of tourists and patients who come to the Bochnia Salt Mine every year. Traditional sightseeing in the historical mining pits has been gradually supplemented by educational, health and entertainment activities. In 2014, “Kopalnia Soli Bochnia Sp. z o.o.” took over the organisation and servicing of the tourist traffic, continuing the long-term tradition of the Bochnia Salt Mine in this respect.

Opis:
Po koncentracji wydobycia węgla z pokładów podredenowskich na pograniczu wsi Dąbrowa i Gołonóg przez Towarzystwo Akcyjne Kopalń Węgla Flora nastąpił okres pojawiania się małych zakładów wydobywczych. Wobec zamknięcia granic polityką celną przed I wojną światową i okresu dobrej koniunktury dla węgla dąbrowskiego trwającej do lat 30. XX w. Towarzystwo wydzierżawiało zbędne dla siebie, z technicznego i ekonomicznego punktu widzenia, części nadań nowym kopalniom. W trakcie spaceru zaproponowaną ścieżką dydaktyczną prezentujemy ich historię, położenie i ślady pozostałe po ich działalności górniczej.
After changes in the organization of mining in the Congress Kingdom caused by the Mining Act of 1870, private mines were created. Five deep coal mines were established on the border between the villages of Dąbrowa and Gołonóg. They exploited little rich, thin seams. The process of merging them into one enterprise called "Flora" Coal Mining Society have taken place almost from 1884 to 1913. The first two enterprises ("Maciej" and "Władysław") were merged in 1902, but their initial organizational division was artificially imposed by applicable law. Other enterprises were taken over by subsequent purchases. Until World War I, the "Flora" Society was profitable due to investment activities and technical changes. Small coal mines in this area were established under lease agreements with the "Flora" Coal Mining Society. Despite much lower production, they were the source of income for many citizens.

Opis:
Desired rock fragmentation is the need of the hour, which influences the entire mining cycle. Thus, most engineering segments pay attention to rock fragmentation and neglect by-products like ground vibration and fly rock. Structural and mechanical properties of rock mass like joint spacing, joint angle, and compressive strength of rock pose a puzzling impact on both fragmentation and ground vibration. About 80% of explosive energy that gets wasted in producing ill effects can be positively optimised, with a new set of blast design parameters upon identifying the behaviour of rock mass properties. In this connection, this research aims to investigate the influence of joint spacing, joint angle, and compressive strength of rock on fragmentation and induced ground vibration. To accomplish this task, research was carried out at an opencast coal mine. It was discovered from this research that compressive strength, joint spacing, and joint angle have a significant effect on the mean fragmentation size (MFS) and peak particle velocity (PPV). With the increase in compressive strength, MFS explicit both increase and decrease trends whilst PPV increased with a specific increase in compressive strength of the rock. An increase in joint spacing triggers both increase and decrease trends in both MFS and PPV. While there is an increase in joint angle, MFS and PPV decrease.

W praktyce oznaczało to, że po szlakach kolejowych mogły kursować pociągi różnych przewoźników. Niestety droga do realizacji tego celu okazała się trudna i dopiero od niedawna można zobaczyć coraz liczniejsze pociągi nowych przewoźników. W artykule omówiono dokonania byłych kopalń piasku podsadzkowego, które w ramach posiadanej koncesji realizują takie przewozy.

Górnictwo od samego początku było zawodem niebezpiecznym, a katastrofy górnicze zdarzały się często. Specyfika warunków środowiskowych podziemnych kopalń, zwłaszcza podczas eksploatacji pokładów węgla, przejawia się występowaniem wybuchowych gazów i pyłu węglowego. Największe niebezpieczeństwo w wyrobiskach górniczych powoduje obecność metanu CH4, który zagraża wybuchem. Objętościowa zawartość metanu od 4,9 do 15,4% w powietrzu powoduje jego stężenie wybuchowe.

Opis:
Research on hydrological changes caused by man has been carried out in the Kręcica basin (A = 62 sq km), situated in the Bełchatów region (Fig. l). Three river gauges, a meteorological station, 8 precipitation stations and 9 groundwater observation wells were established within the study area. Hydrometeorological observations and measurements were carried out regularly and the groundwater level was checked once a week. In addition to basic hydrometeorological monitoring, the study involved: annual hydrographic mapping, preparation of lithological map with hydrogeological sections, regular flow rate measurement, examination of ground permeability and moinsture. The main aim of the study was to grasp moment of the changes in hydrological characteristics, especially of hydrographic network, griundwater and discharge. The research led to the establishment of a formula of water balance of a basin disturbed by man. The basic aim of the formula, was to pinpoint in water retention following the development of a cone of depression created by the brown coal mine in Bełchatów.The analyses presented in this paper indicate, that the changes are quantitave and concern retention in saturation zone and groundwater flow (Tab. l). The result also revealed the moment when a radical disturbance of the natural hydrological cycle in the study area occured. Analyses of climatological features (precipitation, evapotranspiration) have not indicated significant permanent changes. However a significal reduction has been identified when discharge, in particular groundwater discharge (Fig. 4) and a discharge coefficient (Fig. 5) were considered. Explicit changes of retention in saturation zone have also been found (Fig. 6). The results show that the 1983 was crucial in the functioning of the basin. This conclusion has been confirmed by doubly mass curves of annual precipitation and total flow and groundwater flow (Fig. 7). It has been found that decrease in flow caused changes of inclination of the curves. Natural structure precipitation, flow water losses and retention have been replaced by a pattern created by intemtional human activity. The mine drainage, has led to the lowering of groundwater levels and to the development of cone of depression. The cone of depression is increasing gradually and comprises a growing part ofthe Kręcica basin (8-9% in 1980---1982, 30% in 1990). It has led to changes of ground and surface alimentation of watercourses and has caused water escape from river channels. Most of the study area has become one withought surface and groundwater flow. The hydrological changes caused by the mining enterprise, and presented here, are certainly not complete. It should be stressed that the changes are continuing and althought their direction is known, the effects cannot be predicted accurately.
W artykule autorzy zmierzają do przedstawienia wpływu antropopresji na mechanizm obiegu wody w zlewni K.ręcicy. Ukazano kierunki i siłę zmian warunków wodnych w latach 1981-1989. Szczegółowej analizie poddano zmiany sieci hydrograficznej, wód podziemnych i odpływu. Podjęto również próbę analizy bilansu wodnego zlewni. Przeprowadzone badania dowiodły, że wyrażna zmiana w sposobie obiegu wody w zlewni nastąpiła w 1983 r. Należy zatem uznać, iż od tego momentu charakter krążenia wody w dorzeczu istotnie zależy od działalności człowieka.

Opis:
The authors of the paper describe the way in which the longitudinal working Gussmann was mined in level V and the longitudinal working Kosocice in level VI, which in both cases resulted in a water flux from behind the northern boundary of the salt deposit. Only after concrete dams were seated on both levels, the brine flux was stopped leaving a direct contact of the dams with the pressurized water around the mine. For the sake of controlling water beyond the dams, steel pipelines were conducted through both dams and equipped with gauges before the dams. Their use in a saline environment, the developing corrosion increased the possibility that the tightness of the pipelines would be damaged. For this reason a decision was made to protect the mine by making a tight reconstruction of the safety pillar in both levels along the longitudinal working for about 600 m from the dams eastwards. For this purpose the pipeline injection method was applied. As the volume of voids to be tightly filled equaled to about 3800 m3, the task had to be divided into stages. Because of considerable distances of the liquidated workings from the closest shaft, the sealing slurries were prepared in a special injection center on the surface from where they were transported to the destination with a pumping pipeline through the Kościuszko shaft. The most important aspect of liquidating the end parts of the longitudinal working was to properly select the sealing slurries in view of their best cooperation with the rock mass, and such parameters as tightness, durability and cost. At the end stage of works, both longitudinal workings were equipped with dams, which were sealed up with the hole injection method. The innovative technology was implemented in the Wieliczka Salt Mine to reconstruct the safety pillar in levels VI and V in the most westward workings, the mine was shortened by about 600 m, the length of the ventilation system was reduced, systematic observations and pressure read-outs in dams 3 and 4 were systematically eliminated in dams 3 and 4. In this way the costs were lowered and safety of the mine improved.

Badaniami objęto obecność promieniowców w komorach sanatoryjnych kopalń soli w Bochni i Wieliczce w okresie od października 2001 roku do września 2002 roku. Promieniowce Actinomycetes są jednym ze wskaźników zanieczyszczenia powietrza. W obu kopalniach stwierdzono obecność tych mikroorganizmów. Więcej było ich w Kopalni Soli w Bochni niż w Wieliczce. Skład gatunkowy tych drobnoustrojów był bardzo zbliżony w obu kopalniach. Dominował rodzaj Streptomyces. W obydwóch kopalniach można powietrze w komorach sanatoryjnych uznać za niezanieczyszczone promieniowcami.
The occurence of Actinomycetes in sanatorium chambers of salt mines at Bochnia and Wieliczka was studied in the period from October 2001 to September 2002. Actinomycetes are one from among the indicators of air pollution. The presence of these microorganisms was stated in both mines, however in Bochnia salt maine the microbes were stronger represented. The specific composition of these microorganisms was very approximate in both mines: genus Streptomyces predominated. Considering the number of occured microbes the air in chambers of both salt mines may be estimated as unpolluted by Actinomycetes.

Opis:
On the beginning, there had been characterised Katowice Coal Holding Stock Company - one of the largest consumers of energetic media in Poland, which, in second part of 2002 year entered a competitive electrical energy market and for a number of years carries on optimising process of its consumption. Subsequently there was talked over particular stages of rationalization of energetic media consumption. Much attention was dedicated to initiated program that refers to aspect of "daily quality and quantity controlling" and "monthly cost and financial controlling". There was shown its mission, objectives and peculiarity of its working in hard coal mining craft. The description of the energetic media management program is crowned with presentation of consumption level and gained effects in years 1996-2004 for particular energetic media. There has been proved that active management of energetic media returns positive financial results. Summation of Katowice Coal Holding, Stock Company activity in the field of media management in years 1996-2004 gives following reduction for one ton of produced coal: - in unitary consumption of electrical energy by ~ 16,8 %, - in unitary consumption of thermal energy by ~ 46 %, - in unitary consumption of compressed air by ~ 29 %, - in unitary consumption of drinkable water by ~ 38,2 %.

Opis:
Underground mining operations are a very problematic task, especially in poor geotechnical conditions. The right choice of excavation and support techniques leads to adequate and secure mining operations. This should ensure the overall stability of the underground mine with the best productivity and stability performance. In this paper, an empirical model for obtaining support systems for underground galleries was applied. Then, a numerical model for the evaluation of the performance of support measures for rock masses in the Boukhadra iron mine was introduced. Extensive field and laboratory tests were performed to obtain geological, geotechnical, and mechanical data on the entire geologic formations of the (1105 m) level. The performance of the design is supported by the selection of a common support plan between RMR, Q, and UBC systems for each geotechnical unit. Therefore, the rock masses classification based on the geo-mechanical model has determined the suitable support systems. The finite element model (FEM) was used for the analysis of rock mass behaviour, displacements, stress, and plastic point distribution. The results permit the optimization of the plastic zone thickness around the gallery. The outcomes of this study could improve the stability of the mine by choosing the right direction of excavation in consideration to the direction of the discontinuity planes. In order to choose between the current and the recommended mining operations, an equivalent calculation sequence was verified. Our study demonstrated that the consideration of discontinuity sets in the orientation of excavation highly improves the mining conditions with or without support.

Opis:
Miasto Freiberg kojarzy się nam z górnictwem rud cynku i ołowiu oraz pozyskiwaniem srebra. Niestety, teraz to jedynie historia, bowiem kopalnie tego rejonu zakończyły wydobywanie cennych kruszców u schyłku lat 60. XX w. Akademia Górnicza we Freibergu, słynna Bergakademie, jest natomiast w dalszym ciągu chlubą tego 40-tysięcznego miasta, położonego w Saksonii u podnóża Gór Kruszcowych, czyli Rudaw, i odległego od polskiej granicy w Zgorzelcu jedynie o ok. 1,5 godziny jazdy samochodem.

Opis:
W komorach sanatoryjnych w kopalniach soli w Bochni i Wieliczce jest prowadzona tzw. subterraneoterapia, czyli forma leczenia pacjentów z wykorzystaniem specyficznych właściwości bioklimatycznych. Badania mikrobiologiczne w tych komorach wykonywano w okresie od X 2001 do IX 2002 roku analizując skład ilościowy i jakościowy bakterii wskaźnikowych. Zalecanymi przez Polską Normę drobnoustrojami wskaźnikowymi, wskazującymi na możliwość występowania w powietrzu mikroorganizmów chorobotwórczych są bakterie hemolityczne oraz gronkowce. Ilość bakterii α-hemolizujących w komorach sanatoryjnych w Wieliczce mieściła się w granicach od 0 do 50 jtk w 1 m³, natomiast w Bochni od 0 do 121 jtk w 1 m³. Z kolei liczebność bakterii β-hemolizujących unoszących się w powietrzu w sanatorium w Wieliczce mieściła się w przedziale pomiędzy 0 a 36 jtk w 1 m³, natomiast w Bochni - pomiędzy 0 a 83 jtk w 1 m³.
In sanatorium chambers of the salt mines in Bochnia and Wieliczka the subterraneotheraphy is being conducted, as a form of patients’ treatment at utilization of specific bioclimatic proprieties. In the period from October 2001 to September 2002 the microbiological investigations were carried out in there chambers to analyse the quantitative and qualitative composition of indicatory bacteria. The hemolytic bacteria and staphylococci are recommended by Polish Standard as indicatory micro-organisms pointing at possible occurrence of pathogenic microorganisms in the air. The number of α-hemolytic bacteria in air of sanatorium chambers at Wieliczka salt mine ranged from 0 to 50 cfu per 1 m³, while at Bochnia from 0 to 121 cfu per 1 m³. Number of β-hemolising bacteria in the air of Wieliczka sanatorium comprised 0 to 36 cfu per 1 m³, whereas in Bochnia 0 and 83 cfu per 1 m³.
