2008—2019年我国煤矿水害事故统计及演变趋势分析

Evolution trend and statistical analysis of coal mine water disaster accidents in China from 2008 to 2019

为深入探究我国煤矿水害事故发生规律及特点,揭示事故演变趋势,更新事故统计和分析情况,确保相关研究的时效性,对国家煤矿安全监察局、中国煤矿安全网、各省(自治区、直辖市)煤监局等网站公布的关于2008—2019年间我国发生的煤矿水害事故信息进行汇总,利用数理统计的方法从空间、时间、突水水源、矿井类型4个维度进行研究。经分析可知:山西、贵州、黑龙江3省份为水害事故集群性发生区域;每年3—8月为水害事故多发时段,每日3:00-5:00、9:00-11:00、16:00-18:00、22:00-24:00等时段发生事故比较集中;老空(窑)水为水害事故的主要突水水源;将统计年限内的事故起数和死亡人数变化趋势划分为峰前递增阶段、峰后前期递减阶段和峰后后期平缓下降阶段。

In order to deeply explore the occurrence rules and characteristics of coal mine water disasters in China, reveal the evolution trend of accidents, update accident statistics and analysis, and ensure the timeliness of relevant research, the information about coal mine water disasters in China from 2008 to 2019 published by the State Coal Mine Safety Supervision Bureau, China Coal Mine Safety Network, and coal supervision bureaus of all provinces(autonomous regions and municipalities directly under the central government) were collected using the method of mathematical statistics, this paper analyzes the four dimensions of space,time, water inrush source and mine type. The results show that: Shanxi, Guizhou and Heilongjiang are the cluster areas of water disaster accidents;the frequent occurrence period of water disasters is from March to August every year, and the accidents are relatively concentrated in the periods of 3:00-5:00, 9:00-11:00, 16:00-18:00, 22:00-24:00 every day;old goaf(kiln) water is the main source of water inrush;the number of accidents and the change trend of death toll within the statistical years are divided.They are increasing before peak, decreasing after peak and decreasing gently after peak.
