Abstract:
Through analyzing the relationship among safety, source of danger, hidden danger and accident, we propose the concept of "safety shell", and achieve that hidden danger is from "safety shell" failure of hazards; accident is from "safety shell" failure of hazards and hidden danger. "Safety shell" is formed from the safety measures of hazards and hidden danger, which are controlled by human unsafe behavior, unsafe state of equipment, and unsafe conditions of environment, design defects and management faults. On the basis of the theoretical knowledge, the closed loop management pattern and risk early-warning system of hierarchical control are built by information integration and control of hidden danger from corporations, mines and work teams. In the case of Haohua Energy Resource Company, the information system is built with the information integration from check, early-warning and treatment for hidden danger. The system not only improves the scientific nature and effectiveness of coal mine safety management, but also achieves good safety and economic benefits.
