This paper will propose a whole new viewpoint about building a CSPMS(Coal-mine Safety Production Management System) by means of information technology. This system whose core part is a four-grade automatic triggered warning system achieves the goal that information transmission will be smooth, nondestructive and in time. At the same time, the system provides a comprehensive and collective techn...

Coal mine belt conveyor can guarantee the coal mine production stable and efficient. On how to effectively predict abnormal accident occurrence time, this paper puts forward a method to predict the abnormal accident occurrence time based on Hidden Markov Model and Hidden Semi-Markov Model. Large amount of time series is collected through belt conveyor protection sensors. The corresponding HMM o...

Výpočet možnosti vzniku průtrže v dlouhých důlních dílech The article brings results of the evaluation of a possibility of coal and gas outburst origin on the basis of calculation of active forces that try to induce an outburst and passive forces that prevent an outburst from occurring. The analysis of outbursts from the Paskov Mine, Staříč plant, shows that decisive indicators, by which a pron...

Up until 30 years ago, coalminers relied on canaries as warning systems against harmful gases and pollutants underground. The miners listened for birdsong and if the birds fell silent, then they knew there was danger to their health and to take action. Today we have much more sophisticated information and reporting on the quality of air. We know precisely the levels and composition of pollutant...

Mobile communication system for underground coal mines is far more behind the one on surface for the unique underground tunnel environment and safety requirements. Though our previous CDMA System V1.0 can solve the problems of coal mine communication well in regular environments, it still remains a challenging issue for emergency handling. In this paper, we propose a novel integrated RFID and s...

This paper first focuses on the concept of coal entrepreneurial social capital under the background of safety production; Then, analyzes the source of coal entrepreneurial social capital and their action mechanism in order to improve the performance of safety and economy; Finally, this article puts forward the possible application safety production fields and its prospect of entrepreneurial soc...

The production environment of coal mine is complex and tough, so once dangerous situation appears it requires coal miners take accurate and effective emergency measures. Actually, the occurrence and further expansion of a large number of mining accidents are associated with coal miners’ mishandling of emergency. Therefore, evaluating coal miners’ emergency response capacity is the significant w...
