Abstract


Coal is the most import basis for energy and industrial raw materialsin China’s energy, and the coal industry is an important basic industry topromote economic development, it is the basic guarantee for the economicdevelopment and is directly related to the economic lifeline of the Country. Atthe same time, coal industry is a high risk industry which causes a large numberof casualties. From2011, the death toll of colliery accident has dropped under2000. Over view of worldwide, coal mine of China is the most dangerous one. According to the safety condition, the coal mine safety problems not only restrict the coal mine development, but also influence China’s reputation over the world.The research of this paper is based on coal mine safety production of China. Through analyzing the characteristics of coal mine accidents, this paper establishes a comprehensive evaluation index system which based on the domestic existing researches. Then a fuzzy comprehensive evaluation method based on the improved analytic hierarchy has been used for coal mine safety comprehensive evaluation.Thus, the research contents of this paper are as below:(1) To build an index system of Safety comprehensive evaluation. This article points to the analysis of safety management for all size of mines. Through reading a large number of literatures, official laws and regulations, and on basis of the prototype of safety management from Jilin province Hua’an coal industry Shuangyang coal mine to establish the index system of Safety comprehensive evaluation. This index system has successful experience of achievement to go by, which is suitable for coal mines to carry on the safety evaluation.(2) This text combines Hybrid accelerating genetic algorithm with analytic hierarchy process (AHP), then use this improved method to count the weights of the index system. And this method changes the solving of weights and converting judgment matrix into a problem of Non linear function optimization. At the same time, drawing support from improved genetic algorithm—Novel Hybrid accelerating genetic algorithm get the much accurate value of weights. Finally, the evaluation accord from the fuzzy comprehensive evaluation is a realistic result.
