為得到瓦斯突出事故發生的一般規律,減少重特大瓦斯突出事故的發生,統計分析了95起重大及特別重大煤與瓦斯突出事故的時間特征、空間特征及事故礦井基本特征,研究結果表明:煤礦監管部門應重點監管湖南、貴州、河南、重慶、四川等省市的煤礦安全工作,將防突工作的重點放在小型礦井和鄉鎮煤礦,同時要采取相關措施嚴禁非法違法組織生產;煤礦企業應重點加強春節前后、早班和中班時間段,煤巷掘進面、石門揭煤面和采煤面的防突管理,非突出礦井也應加強突出預警和預控工作。研究結論為從宏觀上采取措施預防煤與瓦斯突出事故提供了參考依據。

Abstract:To obtain the general characteristics of coal and gas outburst accidents and reduce the frequency of major gas outburst accidents,statistical analysis of the 95 major coal and gas outburst accidents is conducted from the aspects of time characteristics,space characteristics and the basic characteristics of the coal mines.The results show that the coal mine regulatory authorities should focus on the safety management of coal mines in Hunan,Guizhou,Henan,Chongqing and Sichuan province,should focus on the gas outburst prevention of the small mines and the village and township coal mines,and should take relevant measures to forbidden the illegal organization of production;coal mines should focus on strengthening the gas outburst prevention management in the period of before and after the Spring Festival,in the time of morning shift and swing shift,and in the workplace of coal heading face,rock cross-cut coal caving face,and coal mining face;the non-outburst mines should also strengthen the early warning and pre-control work for gas outburst prevention.The conclusion provides a reference for coal and gas outburst accident prevention from taking macro measures.

在國內煤礦安全生產形勢不斷好轉的情況下,重特大煤與瓦斯突出事故仍時有發生。自2014年1月以來我國煤礦就發生了6起重大及特別重大煤與瓦斯突出事故,共造成70人死亡[1]。可見完全杜絕瓦斯突出事故的發生在短時期內是很難完成的目標,我國《安全生產“十三五”規劃》[2]也指出要“遏制重特大事故頻發勢頭”,所以重大及特別重大瓦斯突出事故仍是煤礦企業防治的重點。因此本文主要研究重特大瓦斯突出事故發生的一般特征規律,為進行事故預測預防及安全決策提供參考依據。……
