Opis:
The paper presents the plight of KGHM Polska Miedź SA due to by the fall in copper prices on global stock markets. It has been noted that these prices apply to smelting copper. Meanwhile, the copper is in increasing quantities supplied to China in the form of concentrates. This causes a drop in prices of smelting copper which becomes less popular. Statistics since 2012 have recorded a permanent surplus of consumption over production of this metal. Therefore, the price of smelting copper will probably be at low level over the next years. It poses a threat for the future existence of the company. The exploitation of new deposits is conducted at a depth of below 1200 m. The rock temperature is about 55°C, which creates technical and financial problems. Mining work is carried out along the dip of the deposit at increasingly greater depths. In this direction, 10 km away, there is the “Wilków” natural gas field. It is proposed to undertake diversification of mining activities. Gold mining seems to be the prospective activity. Its economic concentrations occur in the mines of the KGHM, in the Lower Silesia region and abroad. Likewise, the company can achieve positive effects in investments related to the mining of diamonds.

Opis:
After World War II, Jan Wyżykowski studied at the Faculty of Mining University in Kraków. In 1946-1948, he held summer practices in mines and at the Polish Geological Institute (PGI), which allowed him to explore the ore deposits in Lower Silesia. On January 1951, he was transferred to the PGI, where all works related to the issues of the ore exploration were gradually taken over by the Ore Department based in Kraków. In the early 1950’s, a research program for copper exploration began to crystallize in the area located north of the Old Copper Basin and north of Wroclaw. Such program was postulated by two heads of the Ore Department, R. Krajewski and A. Graniczny. A seismic profile was acquired along the Boleslawiec-Glogów line to determine the extent of the Zechstein Kupeferschiefer formation in the Fore-Sudetic area. Wyżykowski was a planner ofthe drillings along this profile. Thefirst three boreholes did not indicate the possibility of success. What is more, Wyżykowski’s research was illegal, because he drilled to a depth of 700 metres, which was about 300 metres deeper than allowed. The thesis offutility of exploration in this area started to dominate. Despite all these adversities, Wyżykowski stubbornly strove to achieve the goal. A team led by him came across economic copper ore deposits on 23 March, 1957. In the Sieroszowice IG 1 borehole, at a depth of650 m, copper mineralization of 1.4% was found in marls. The presence of rich copper mineralization was confirmed also in a nearby borehole drilled in Lubin, S-19. The history of the "great Polish copper has started”.

Opis:
The paper presents a brief history of the origin and development of the “Konrad” copper mine located in the Grodziec Basin near Boles³awiec. Analysis of the decision on its close down in 1987 is provided. A two-page document stated that the former mine had been “permanently unprofitable”, without relying on the documents and facts in this case. Studies justifying this decision arose only several years later in a completely different economic situation. The mine sinking process was described. It encountered unforeseen problems with the simultaneous close down of a prosperous source of drinking water for the nearby villages. Currently, many professional communities and local governments put foreward proposals for the re-running operation on the deposit. The direct cause of this type of applications is the former foreign failure of the mine’s owner, which previously was Kombinat Górniczo- Hutniczy Miedzi in Lubin and currently KGHM Polska Miedź SA. A justification for this kind of concept is that the copper content in domestic deposits is several times greater than in the deposits purchased in the US, Canada and Chile.

Opis:
Since 1989, KGHM Polish Copper SA has become increasingly open to the world market for raw materials. In 1992, the Asacro Company from the US is trying to take over the KGHM PM SA. This is prevented by a strike of miners and steelworkers of this company,lasting 32 days. Since then, no attempts have been made to take over the company. Foreign investors are effectively deterred by one of the world’s highest production costs of copper – 1.82 USD/lb Cu. The cost of production of one ton of Cu had been 5227 USD by 2015. One of the reasons is an inefficient mode of mining. The start of mining from the uppermost part of the deposit means that some parts of the deposit cannot be, because it creates a threat to the sections operatingat lower levels. Similarly, mining works conducting from the wells to the boundaries of the deposit causesthe necessity to move to new areas of exploitation across already exploited parts of the deposit. It is proposed to eliminate these difficulties by directing the mining extraction process using an electronic control system that allows obtaining immediately the desired changes. The example of the Robert Friedman’s school of prospecting for new copper ore deposits, it is recommended to restoret he Polish school of prospecting for deposits, this time on a global scale for the needs of the KGHM Polish Copper SA and the Polish mining industry.

Opis:
The issue of three-dimensional geological modelling of stratoidal copper and silver ore deposit in the Fore-Sudetic Homocline has been the subject of hot discussions for many years. Formation of a single layer of deposit body can suggest the ease of interpretation of its form and structure, putting into question the need of three-dimensional visualization. The problem of building and updating a model is directly related to the production scale of KGHM Polska Miedź S.A. which is held over an area of495 km2 with an annual progression of around 480 km of underground workings in three mines, which also includes additional exploration of the deposit body. An important step in the time-consuming 3D geological modelling process is the appropriate selection of previously prepared data and the spatial dimension for the target model - in accordance with its intended purpose. The process of 3D geological modelling, currently carried out at KGHM Polska Miedź S.A., can be divided into two related steps: structural modelling and grade modelling. The components of structural models are used in the grade modelling process, acting as a set of geological constraints during the grade estimation process. The products of both steps find practical application in many processes in a mining company.
