Studies Of Coalmine Safety Evaluation And Application In Driving Production System

Complexity of mining extracting decides that safe evaluation in mine is a complicated system engineering. Coalmine accidents restrict production of coalmine seriously. People recognize mine accidents for a long period of time, but hardly realize that many accidents exist in production of coalmine driving.This thesis analyzes current situation of coalmine safety, which points out the importance of coalmine production. It contacts the realistic situtation of coalmine production, the principles and essences of safety evaluation are expounded, and the importance of safety evaluation is presented.Firstly safety evaluation index system is analyzed, which explains methods of identification of dangerous and harmful factor. This thesis analyzes causes of dangerous element of coalmine driving and how it comes to being. Then the evaluation system is specially used in coalmine driving production and each evaluation element is analyzed.The thesis establishes safety evaluation model on the basis of the realistic coalmine driving safety index system, and with fuzzy general evaluation method applied to evaluate the results of evaluation. The results accord with coalmine realistic situation, we can solve safety problem of the coalmine driving production based on the evaluation rush. The method firstly gives out the standard of coalmine driving safety evaluation .It has great important effect on guiding coalmine driving production.
