Theory and Construction of Emergency Refuge System in Underground Coal Mine

Abstract

According to the improving construction requirements of emergency refuge system in underground coal mine, key issues to be solved in construction of emergency refuge system were listed as follows, safety investment deficiency, lack of legislative guarantee, imperfect evaluation system, unreasonable system structure design, education and training lag. Emergency refuge theory and practice of underground coal mine in mining developed countries were studied by comparison and Induction methods and the results show that good safety refuge system can effectively reduce casualty caused by mine disasters. Methods of building emergency refuge system in underground coal mine were proposed, that were, establish coal enterprises and government and banks trinity of financing model, improve and regulate the cost of accident, sound disaster evaluation index, build emergency rescue system based on refuge facilities, design on the whole system structure. Based on accident causal chain theory, emergency management theory and ideas of modern occupational safety and health management system, financing model of safety investment, emergency rescue model based on refuge facilities and structure of emergency refuge system in underground coal mine were designed, which would provide theoretical basis and mode guidance for improving construction of emergency refuge system in underground coal mine.
