Study on Optimization of Coal Mine Safety Risk Evaluation Index System

Abstract

In view of the problems that current coal mine safety risk evaluation index system cannot meet the dynamic safety evaluation of coal mine risk, lack of comprehensive evaluation of multi-specialty and the whole process, through the study of risk factors affecting coal mine safety production and the current situation of index system construction, a general index system of coal mine safety risk evaluation is constructed, and the analytical hierarchy process (AHP) and correlation score are used by analyzing the subjective and objective index screening method, optimizing the index system, and combining with the safety production practice of Hongqingliang Coal Mine of Haohua Energy Company, the safety risk evaluation index system which accords with the mine is obtained. The results show that the index system can truly reflect the comprehensive risk of the mine, and effectively improve the accuracy of the mine safety risk assessment.
