The Fundamental Theory And Practice Of Coal Mine Safety Fuzzy Comprehensive Assessment

Risk assessment of coal mine with the propose of carrying out the coal mine safety,analyses existent dangerous and harmful factors of wells and miners,judges the possibility and its serious degrees of mine accidents in the course of the coal mine productions. And the result can be provided scientific proofs about guarding against the accidents and establishing manageing decisions.In this paper we take up all kind of influence factors on mine safety,and conceived evaluation index system on mine safety. This system considered every influencing factor on mine safety.On the base of former evaluation method this paper try to evaluate every factor in index system .So Fuzzy Synthesis Safety Assessment is used in this paper. The merits and faults of evaluation methods were analyzed and 24 factors in 4 species were used to evaluate the safety of mine. First it used method of expert survey to built the membership grade of index, and then confirmed the weight by using Analytic Hierarchy Process. At last conclusion was drawn by using multiple target Fuzzy Synthesis Safety Evaluation. This method is good at changing qualitative analysis into quantitative analysis and making logical judgement by scientific mathematics calculate.Fuzzy Synthesis Safety Evaluation calculation was made on the base of mathematics model. This method was used in actual evaluation the good effects acquired. It proved that this method of Fuzzy Synthesis Safety Evaluation is feasible to existing evaluation method.
