Based on the rigorous situation of safety production in coal mines, the paper analyzed the statistical data of recent accidents indexes in Henan's coal mines. Using investigation and comparison analysis methods, a specified analysis on mining conditions, technical facility level, safety input and vocational quality of workers in Henan's coal mines was conducted. The result indicates that there have been existing such main safety production problems as weak safety management, low-level facilities, inadequate safety input and poor vocational quality and so on. Finally it proposes such reference solutions as to establish and perfect coal mining supervision and management system, to increase safety investment into techniques and facilities and to strengthen workers' safety education and introduction of more high-level professional talents.

A method system was put forward based on the occupational health and safety management system to develop the dynamic safety management of coal mine. It aimed at the problems in the mining safety management and was put in practice in Lingxin coal mine of Ningxia Coal Industry Group Co., Ltd.. And good effect was obtained in safety work. It developed the mining dynamic safety management based on the building of occupational health and safety management system of mining enterprise and its main contents are as follows: timely identification and dynamic control of accident risk, persistent improvement of safety management performance according to the "PDCA" circle.

Based on safety management appraisal theory, the decision system was divided into 5 function menu module, including system control module, mining coal and the tunneling working surface security evaluation module, the entire ore safety production condition appraisal module, the safety management level appraisal module of main production work area, the withdrawal system module and so on. The system operates through the constitutive procedure, outputs the main operation results by graph and form,and realizes the main function of safety evaluation.

The key issues studied focused on underground coal mining and included (1)prevention of explosions in sealed areas, (2) better emergency preparedness and re-sponse, (3) improvement of miners' ability to escape, (4) better protection of miners beforeand after a fire or explosion, (5) improved provision of oxygen, and (6) development andimplementation of more robust post-incident communication. The U.S. Congress passedthe Mine Improvement and New Emergency Response Act of 2006, which mandated newlaws to address the issues. Concurrent with investigations and congressional deliberations,the National Mining Association formed the independent Mine Safety Technology andTraining Commission to study the state-of-the-art relative to technology and training thatcould address the vulnerabilities exposed by the mine disasters. As discussed, the reportoutlined persistent vulnerabilities linked with significant hazards in underground coal mines,and made recommendations to provide a path for addressing them. Overall the commis-sion report made 75 recommendations in the areas of risk-based design and management,communications technology, emergency response and mine rescue procedures, trainingfor preparedness, and escape and protection strategies. In its deliberations, the commis-sion importantly noted that mine safety in the U.S. needs to follow a new paradigm for en-suring mine safety and developing a culture of prevention that supports safe production atthe business core. In the commission's viewpoint, the bottom line in protecting coal minersis not only adopting a culture of prevention but also systematically pursuing mitigation ofsignificant risks.
