2000-2015年我国煤矿水害事故特征分析

摘要

针对我国煤矿水文地质条件复杂、水害事故频发的现状,通过整理国家煤矿安全监察局和国家统计局2000-2015年数据资料,以折线图、柱状图、饼状图等形式,对近16年煤炭产量、煤矿事故情况和水害事故情况进行年度分类,并对三者之间的关系进行探讨分析,揭示了我国煤矿水害等级特征,探讨了事故发生的时间特征与国家相关政策规定的关系.结果表明:水害事故依然是煤矿事故的第二大杀手,2000-2015年期间较大以上水害事故发生起数和死亡人数均占煤矿事故起数和死亡人数的18.7％,重大水害事故单起死亡人数最多,这将对"十三五"期间我国煤炭行业发展提出理论支撑.%According to the complex hydrogeological conditions and frequent occurrence of water inrush accidents in China′s coal mines,through the consolidation of National Coal Mine Safety Supervision Bureau and the National Bureau of statistics data from 2000 to 2015,in line chart,histogram,pie chart and other forms,the author makes annual classification of coal production,coal mine accidents and water inrush accidents in the last 16 years,and analyzes the relationship between the three,reveals the level characteristics of water disaster accidents,discusses the relationship between the time of the accidents and relevant national policies and regulations.The results show that the water inrush accident is still the second largest killer of coal mine accidents,the number of major and grave water disaster accidents and deaths accounted for 18.7％of the total number of coal mine accidents and the deaths during 2000-2015.Single grave water inrush accident has the largest number of deaths and must be paid more attention to,which will offer theoretical support for the "13th Five-Year" during the development of coal industry in China.
