Study On The Coal Mine Safety Assessment Based On Unascertained Theory

Coal industry is the important foundation of our national economy development, but the coal mine industrial accidents have restricted the coal mine production seriously and brought the life and the property damage to some person even to the country. Conducted scientifically and rationally safety assessment on the coal mine enterprises, which is not only to promote coal mine safety in production enterprises, but also to comprehensively and effectively enhance the level of safety management of the coal mine enterprises. So it is particularly important to carry out the safety production for the coal mine enterprises.This thesis has analyzed the advantage and disadvantage of the several common assessment methods on the coal mine at present, after that introduce the assessment method of unascertained measure which is based on the unascertained mathematics theory. Combined the unascertained measure theory and the data of the BOFANG coal mine, established the assessment index system and divided the assessment of space, and then confirmed weigh by using entropy, at last established the BOFANG coal mine comprehensive safety assessment model, and got the level of security of coal mine by using the assessment model ,put forward safety measures, as well as had the important significance in controlling the coal mine accidents.
