Factors of work environment hazardous for health  in opinions of employees working 
underground in the ‘Bogdanka’ coal mine

Accident is undesired to anyone. But the research shows that the main cause of accident is unsafe behavior. The interaction mechanism of accident system was analyzed in the process of gas explosion through typical accidents and the conclusion was that the accident was occurred because unsafe behavior induced the dangerous factor in work environment. In order to further acquaint of it, the situation cognition of workers in the coal mine production process was analyzed with the research of aviation. The cognition of safe information in work process was affected by workload, goal, work habituation and others. As workload increased, goal strengthened, the attention apperceived safe information is weaken and the major change of safe information wasn’t apperceived immediately in work environment, and the accident was happened in conditions of unsafe behavior. Finally, the accident model based on situation cognition was posed and some measures were proposed.

Safety Improvement

Abstract Exploitation of coal from the Jiu Valley presents its own specific, in terms of coal mining deposit conditions, fact that required a continuous preoccupation for the monitoring of the work conditions, in order to ensure work-places safety. This paper intends to indicate a method of increasing the work environment safety using GIS technology, the analysis being completed at Lupeni Coal Mine, the largest Coal Mine in Jiu Valley, characterised by a low level of accidents that has taken place in there so far. It consists of an extension of accomplished studies in order to implement an intelligent dispatching system.

Derivation Process

To meet the special needs of the bolting and shotcreting work environment of coal mine, a new pneumatic spring-piston mechanism was designed. The derivation process of the pressure loss equation was described based on S.Morinaga formula. The concrete pumping machanism kinetic model was constructed and analysed using Lagranges Equation. The work of this paper lays a theoretical foundation for optimization design of wet spraying machine system.

End support on coal face is an important equipment of improving the work efficiency and the safety of coal mine production. Based on the work environment and the requirements for end support, the research analyzed the mechanical design of end support, such as its structure and composition. Moreover, several features which need to be paid attention to in the design of end support were proposed as well.
