Outlined the South African mine health and safety regulatory framework, including the roles of government, tripartite council, service agencies, mine enterprises,rescue stations and workers unions, analyzed the institutional structures of South African mi
Function simulation, which is called virtual reality too, is popularly applied to solve uncertain problems. Good performance of hidden layers and perfect capability of function simulation make artificial neural networks one of the best choices to simulate
Aiming to the deficiency of safety management measure, established simulation model about firm\'s safety management capability(FSMC) based on organizational learning theory. The system dynamics(SD) method was used, in which level and rate system, variab
Improved wavelet analysis in enhancing Electromagnetic Campatibility of underground monitoring syste
Underground Electro Magnetic Interference (EMI) has become so serious that there were false alarms in monitoring system, which induced troubles of coal mine safety in production. In order to overcome difficulties caused by the explosion-proof enclosure of
Analyzed of the present situation of Chinese coal mines safety in production and the reasons for coal mining accident, and realized the coal mines safety in production,which should increase the legal safeguards of coal mine safety in production, and safet
Based on economics theory, social value loss caused by vehicle involved in crashes as well as various factors influencing on it were analyzed, the corresponding micro-econometrics model was theoretically given. Moreover, the practicability of the model,th
Pressure-relief effect of coal rock body of long distance lower protective seam mined based on FLAC3
According to the specific geological condition, analyzed the stress distribution of the overlying strata, the displacement of pressure released seam, thickness variation and the distribution of plastic zones by FLAC3D software to simulate mining of the lo
Described the main environmental hazards occurring in Polish underground mines and their continuous growth in recent years as well as equipment and systems which were used for monitoring mine air parameters and geodynamic phenomena. The latest versions of
