Opis:
As the major industries, mining has high potential risk of accidents. Historically minerals have supported humane development and civilization but at the same time this industry has been accompanied by accidents, often with disastrous consequences. Number of mine accidents worldwide, as well as in the Stan Terg mine is disturbing, even more disturbing is the fact of the repetition of the causes of mining accidents. This investigation aims to analyze the causes of accidents, tending to provide the accidents prevision through risk assessment. For this purposes various data and documents, related to accidents in the Stan Terg mine have been analyzed, as well as international documents and statistics related on mining safety and accidents. Whereas, the time period of 2007–2011 is analyzed as a key study, 306 accidents have been analyzed for this purpose. Accident causes, date and time, accident location, working shift, worker’s age and type of injury have been analyzed for each selected accident. Thus, for this period of time are caused 292 minor injuries, 14 serious injuries and 1 fatality accident, 60–70% of accidents are caused in the production process, 25–35 in the maintenance process, whereas about 2–5% during of monitoring or other types of works.

Opis:
This study investigated the effects of user factors and cognitive sign features on the guessability of mine safety signs. Sixty naive participants guessed the meanings and rated the cognitive sign features of 42 Mainland Chinese mine safety signs. The results showed that some user factors were significant predictors of guessing performance, while some were not. As expected, guessability scores varied significantly with the cognitive sign features of familiarity, concreteness, simplicity, meaningfulness and semantic closeness. The findings emphasize the need to create awareness of the importance of mine safety and promote understanding of mine safety sign meanings amongst people in their work environments. To design more user-friendly mine safety signs, industrial designers should develop and evaluate signs with consideration of the significant user factors and the 5 sign features tested here.

Opis:
The MINER Act of 2006 was enacted by MSHA following the major mining accidents and required every underground coal mine to install refuge areas to help prevent future fatalities of trapped miners in the event of a disaster where the miners cannot escape. A polycarbonate safe haven wall for use in underground coal mines as component of a complete system was designed and modeled using finite element modeling in ANSYS Explicit Dynamics to withstand the MSHA required 15 psi (103.4 kPa) blast loading spanning 200 milliseconds. The successful design was constructed at a uniform height in both half-width scale and quarter-width scale in the University of Kentucky Explosives Research Team’s (UKERT) explosives driven shock tube for verification of the models. The constructed polycarbonate walls were tested multiple times to determine the walls resistance to pressures generated by an explosion. The results for each test were analyzed and averaged to create one pressure versus time waveform which was then imported into ANSYS Explicit Dynamics and modeled to compare results to that which was measured during testing for model validation. This paper summarizes the results.
W następstwie poważnych wypadków w kopalniach, w roku 2006 MSHA uchwaliła Ustawę Górniczą na mocy której wszystkie kopalnie zobowiązane zostały do wyznaczenia odpowiednich stref bezpieczeństwa dla uniknięcia w przyszłości ofiar śmiertelnych wśród górników uwięzionych w kopalni w przypadku katastrofy uniemożliwiającej ucieczkę. Zaprojektowano ścianę ochronną wykonana z poliwęglanów zabezpieczającą strefę bezpieczeństwa w kopalniach podziemnych, jako element całego systemu zabezpieczeń. Ścianę zaprojektowano i modelowano w oparciu o metodę elementów skończonych z wykorzystaniem pakietu ANSYS Explicit Dynamics. Według wymogów MSHA ściana winna wytrzymywać ciśnienia 15 psi (103.4 kPa) w trakcie najsilniejszej fali wybuchu trwającej 200 milisekund. Odpowiedni projekt wykonano w odpowiedniej skali: połowie i ćwierci wysokości, jako obiekt jednolity. Modele zweryfikowane zostały przez badaczy z Uniwersytetu w Kentucky, z wykorzystaniem odpowiedniego tunelu testowego. Ściany wykonane z poliwęglanów zostały wielokrotnie przebadane aby określić ich wytrzymałość na ciśnienia powstające w trakcie wybuchu. Wyniki każdego z testów zostały przeanalizowane i uśrednione a otrzymany przebieg ciśnienia w funkcji czasu został zaimportowany do pakietu ANSYS Explicit Dynamice i zamodelowany, tym samym umożliwiając jego porównanie do wyników pomiarów wykonanych w ramach walidacji modelu. W niniejszej pracy zestawiono uzyskane wyniki prac.

Opis:
Coal mine methane is a term given to the methane gas produced or emitted in association with coal mining activities either from the coal seam itself or from other gassy formations underground. The primary reason for measuring methane is to improve the safety of the mines. In recent years, there have been many fatalities in underground coal mine explosions in which methane was a contributing factor. The rapid detection of methane is very important from the point of view of safety of mine workers. This paper presents a concept of fast methane detection by reconstituting its concentration in dynamic states.

Opis:
The number of mining operations is increasing in the Canadian North, where extreme weather conditions govern. Currently, many mine development projects are also in progress in this region. These mines’ working atmosphere and employment circumstances are highly different from regular mines. One of the main differences is the special safety issues of the Canadian North. The primary sources of these special issues are: the difficulty of finding skilled employees; high employee turnover rate; insufficient training and certification requirements; delicate employment circumstances affecting the psychological well-being of employees; permafrost; mine inspection challenges; inventory and logistic hardship; and the legislative and regulative necessities corresponding to the particular working environment. This paper aims to set forth specific safety cases in the mines located in the Canadian North. Then, it argues the characteristics of safety organizations and management required to deal with these cases. Furthermore, how the current frameworks can be improved is discussed. Safety issues stemming from cold weather conditions and location remoteness of mines add further challenges to the viability and implementation of projects. The paper underlines that mining operations need certain safety organizations, management approaches, and specific regulations for the mines operated in remote areas and under severe weather conditions.

Opis:
In the process of underground mining, the mining system changes for various reasons. One of the main reasons is changes in the mining production plans, especially the scales and outputs. Nowadays, coal mines in Vietnam have been expanding in width and depth, and so have the mines’ ventilation systems. Consequently, there will be changes in the alteration of the structure of the design ventilation system, which reduces the effectiveness of the ventilation and does not meet the main objective of mine ventilation, directly affect the safety of the working environment in the mine. Therefore, it is necessary to research the improvement of the ventilation system with the development and specific conditions of underground coal mines in Vietnam, improving the efficiency of the ventilation work and assuring the safety of the mine environment. Cam Thanh coal mine, Ha Long coal company, Vietnam, is the case study for this research. The article considers the plan of increases the mining output by more than 1.5 times, propose solutions to improve the ventilation system accordingly, helping the company proactively implement the production plan, ensure the working environment's safety, and reduce the costs of mine ventilation.

Purpose: the main purpose of the article is to underline importance of updating knowledge by mine rescuers related to deteriorating geological conditions of mines, that can lead to accidents and events that result in serious disasters. Design/methodology/approach: theses presented in the article have been verified using: literature review, critical literature analysis, document research and comparative analysis. Findings: based on content of this article, mining rescue will be considered as the most important aspect of the entire occupational safety system. The main element in mine rescue is the lifeguard-specialist, who has unique and constantly improving qualifications and professional competences. Hence, the role and quality of mining rescue should be assessed not only in the scope of the tasks that it has to perform, but also perhaps even more importantly, in relation to new challenges that require the constant adaptation of mining rescue to fit dynamically changing organizational and technical conditions, both underground and on the surface of the mine. Originality/value: the article enriches knowledge and develops discussion in the area of mining rescue. Thanks to the knowledge presented in the article, it can be concluded that role and the rank of mining rescue lies not only in the dimension of tasks that it has to perform, but also importantly in the dimension of new challenges that determine the need to constantly adapt mining rescue to dynamically changing organizational and technical conditions, both underground and on the surface of mine sites.

Opis:
The analysis of contemporary military conflicts shows, that the most dangerous threat for soldiers are Improvised Explosive Devices (IEDs). Blast resistance of military vehicles and structures is broadly discussed in many articles. However, information about human body response to impact loading is hard to find and very general. Both experi-mental trials with dummies and numerical analyses are needed. To design and develop better protection system it is necessary to identify and measure the effects of blast wave impact on crew of military vehicle. This paper presents numerical simulation results of special armoured vehicle subjected to mine threat of 8 and 10 kg of TNT. Possible effects of mine explosion on human body are described. Review of modern-mine and IED countermeasure solutions is presented. The analysis is conducted using LS-DYNA explicit code. Only vehicle’s hull is considered with suspension and turret is modelled using mass. Gravity is taken into account. Numerical model of Hybrid-III dummy is used. Accelerations and forces in tibia, neck and spine were calculated. HIC-36 criterion was also evaluated Different types of possible seat configuration are examined. Results show convergence between explosive size and injury risk.

Opis:
The structure of a vehicle located in the explosion area of an anti-vehicle mine or an IED is subject to a strong impact of a blast wave. The explosion of a mine produces a blast wave that travels in all directions at a speed greater than the speed of sound. The level of risk to the crew of a military vehicle depends on their distance from the place of detonation, on the vehicle’s design and in particular on the design of the bottom of the hull and on the assembly and type of seats. The article provides the analysis of the impact of a side explosion on the crew of an armoured vehicle. Since the new classified version of the AEP-55 document, which defines the conditions for testing the resistance of military vehicles to explosions affecting their side, is not available, it was assumed in the numerical analysis that the charge weight of the explosive device is 100 kg TNT, placed between the central vehicle axles at the distance of 400 mm from the bottom and 1,000 mm from the lower board. Two cases were analysed: one where the Hybrid III dummy was placed on the reference seat and the other where it was placed on a modified seat. The analysis is conducted using the LS-DYNA explicit code. Only the vehicle’s hull is considered with suspension and the turret is modelled with mass.

Opis:
The purpose of this study was to assess miners’ perceptions about the safety climate of their workplace. To achieve the research aim, the relationship between demographic characteristics and occupational hazards was first determined, and finally, the relationship of safety climate with occupational hazards and health-seeking behavior was discovered. The data was collected through a self-reporting questionnaire. The results revealed that the subjects have to deal with severe occupational hazards, and they possess poor health-seeking behavior. A safety climate assessment showed that only one of the seven dimensions (i.e. safety communication, learning, and trust in co-worker safety competence) was at a satisfactory level. With respect to the first objective, we found that age, education, and experience were statistically significant with occupational hazards, while marital status had no significant impact on occupational hazards. Regarding the second objective, three dimensions (management safety justice, safety communication, learning, and trust in co-worker safety competence, and workers’ trust in the efficacy of safety systems) were significant predictors of occupational hazards. The study reflects that workers’ participation is the main factor in setting up an adequate safety climate within the organization. Suggestions provided in this study could provide useful information to managers and safety practitioners to improve safety performance and promote the safety climate in the organization.

Within the INESI-project (Increasing Efficiency and Safety Improvement in Underground Mining Transportation Routes) long-wavelength infrared (LWIR) cameras are used for detecting persons on underground belt conveyors or within hazardous areas e.g. in front of crusher or skip vessels by the project partners KOMAG and the Institute for Advanced Mining Technologies (AMT). The test case for evaluating the performance of thermal imaging regarding these applications is the Polish Sobieski underground coal mine operated by Tauron mining company. By the development of thermal image processing algorithms, an automated detection of persons and classification of different objects was achieved. This may allow implementing smart services for person detection on underground belt conveyors as well as material characterization between coal, rock and disturbing objects on belt conveyors.

The article presents information on changes to the mine shaft hoist in the cage compartment of the “Sobieski III” shaft of Tauron Wydobycie S.A. A separate control unit based on MENTOR thyristor converters was installed in the excitation system of the drive motor and control generators, which allowed the replacement of systems that were difficult to operate, e.g. electromechanical amplifier (amplidyne) and the machine exciter of the hoist motor. Additionally, in order to stabilize the speed (especially during revision works in the shaft), the system of setting speed levels of the hoisting machine has been modified. Speed adjustment is realized by a follow-up speed control system built on the basis of a digitally controlled MENTOR reverse converter.
