Underground Mine Is A Major Accident Hazards And The Degree Of Risk Classification

As the legal safety regulations system of our country forms basically, the emergency system of safety in production begins to establish, especially the whole society pays more and more attention to safety in production, it is restrained that the nation-wide overall situation of safety in production tends to improvement. Especially serious safety accidents which are frequently in mining profession have controlled. But it is stern that mining safety in production. Comparing with dangerous chemical safely management system. Mining safety management system still has the great insufficient. It has realistic meaning that how to perfect and strengthen the mining safety management system of our country,This paper first summarizes the mining safety situation, and its reason of our country; by researching dangerous chemical safety management system, the prevention and control hierarchy of serious mining accident have been established, each composition essential factor of system have been discussed. Introducing general linear add function law and principal component analysis (PCA) in comprehensive appraisement, pointing out suitable scope and the good shortcoming of two methods. According to the present situation that now still has no a appraisement of mining dangerous level and grade standard in production. Adduce analysis method that synthesize a kind of appraisement with the biggest dangerous level of hurting for mine that accident may cause , at the same time giving the biggest injury calculation formula , biggest injury people amount of accident is as the mining enterprise dangerous level of safety in production grade standard.Final, this paper utilizes the mining dangerous level analysis method of safety in production of putting forward, as Yunnan a mining company which mined lead and zinc, and a mining company which mined tine, have carried out mining dangerous level analysis, its analysis conclusion conforms toreality, it is feasible to have verified analysis method.
