Law analysis and counter measures research of coal mine accidents in China from 2013 to 2018

Based on statistics of coal mine accident data during 2013-2018 in China, occurrence law and characteristics of coal mine accidents in China were studied from aspects of accident area, occurrence time, coal mine ownership and accident types, which provides basic support for analysis and early warning of regional coal mine safety situation from the macro level.The results show that:① The total number of coal mine accidents in the five southern provinces (cities) accounts for a relatively high proportion, Heilongjiang and Guizhou should be strictly prevented from consecutive major accidents, and the task of prevention and control of major accidents in coal provinces is still arduous.② The resumption of production from March to May after the Spring Festival and the increase in coal demand in the fourth quarter are the main reasons for the high incidence of accidents during these periods.③ Township coal mine accidents account for more than 50% of the total; state-owned local coal mines have better control of relatively serious accidents and major accidents, the numbers of accidents and deaths are below 10% of the total; state-owned key coal mine accidents account for more than 25% of the total, and the major accidents account for more than 35%, therefore, the state-owned key coal mines should be strictly controlled in major accidents.④ The number of roof accidents is the most,and gas accidents cause the most deaths;gas, roof and transportation are the key points to control the total amount of accidents, gas and flood are the key points to prevent and control major accidents. In view of the occurrence law and characteristics of coal mine accidents, the following counter measures and suggestions are proposed from four aspects of industrial policy, key prevention and control objects, technology and personnel, and supervision: further deepen the supply-side structural reform to fundamentally improve the overall safety level of coal industry; targeted control measures should be taken according to the key prevention and control objects identified from the aspects of accident area, occurrence time, coal mine ownership and accident type; increase the input of coal mine safety technology and equipment and strengthen the management and technical ability of coal mine workers; rationally allocate regulatory and supervisory resources and strengthen scientific oversight and supervision.
