【摘要】：为了研究我国煤矿重特大事故的一般规律,分析了2002—2014年我国煤矿发生的421起重特大事故,得到我国煤矿重特大事故的基本特征。利用统计分析法从地域、类型、所有制3个维度综合分析了421起煤矿重特大事故。结果表明:山西、贵州、河南、黑龙江和湖南5个省份的重特大事故起数和死亡人数分别占全国总数的56.1%和56.8%,是我国需重点监管和治理的省份,并对山西、河南和黑龙江3省重特大事故频发的原因进行了分析;瓦斯事故和水害事故的发生起数及死亡人数占比分别为83.3%和86.3%,是需要重点防治的事故类型;国有重点煤矿重特大事故平均每起死亡人数为29.87,且近两年重特大事故起数和死亡人数均大幅度上升,是需要重点防范的对象;乡镇煤矿重特大事故起数及死亡人数下降速度均较快,但事故起数和死亡人数仍较多,是国家重点监控、治理的对象。
[Abstract]:In order to study the general rules of China's major coal mine accidents, analysis of 2002 - 2014 in China Coal Mine occurred 421 crane accidents, get the basic characteristics of China's coal mine accidents.
