Establishment And Application Of Safety Evaluation Index System During Construction Of Hongyi Coal Mine

Coal mine safety investment increasing in recent years,the security situation is getting better,but coal is still a high-risk industry,major workplace accidents to happen from time to tome,for a is the production of the mine,coal mine need to accurately grasp the current security situation,through the evaluation means is a kind of method to solve the problem.At present a lot of research on coal mine safety evaluation,the content is comprehensive,but with the development of science and technology,the decision of the coal mine safety factor are also changing,the previous evaluation index has been difficult to meet the current coal mine security situation,need to target to establish,based on the coal mine safety evaluation index based on a lot of research before combining with the current situation of the development of coal mine,puts forward some new indicators,through the expert investigation,determine the final index system.The index system has been improved.In view of the strong subjectivity of the evaluation index of coal mine,it is difficult to determine the problem.This paper chooses the analytic hierarchy process to determine the index weight of the evaluation system through a large number of investigation and research.In addition to many indicators could not qualitative evaluation process,dimensional not unified problem,use fuzzy mathematics to establish a unified evaluation set,and then combined with the red coal mine,through a large number of membership degree investigation,to determine the membership degree of each factor corresponding evaluation to evaluate the final result is good,that is the overall evaluation of coal mine safety do better,but still there are some problems need to improve,finally,the paper puts forward the countermeasures for raising the level of coal mine safety.
