2010～2015年我国煤与瓦斯突出事故发生时空分布规律研究

Study on the rules of time and spatial distribution of coal and gas outburst accidents in China during 2010～2015

为了了解和掌握煤与瓦斯突出事故发生的规律和特点，本文对我国2010年至2015年间煤与瓦斯突出事故进行了统计整理，分析了事故起数和事故死亡人数与事故的等级、事故的地域性及事故发生的时间性之间的交叉关系，结果表明：2010～2015年间煤与瓦斯突出事故类型中较大事故发生的最多，占事故总起数的68．42％，造成的死亡人数也最多，占总死亡人数的45．68％，突出事故起数和死亡人数最多的省份是贵州省，发生事故起数最多的是8月份，凌晨最容易发生煤与瓦斯突出事故。

In order to understand and grasp the rules and characteristics of coal and gas outburst accidents, the coal and gas outburst accidents from 2010 to 2015 in China are sorted - out in statistics. The cross coupling relationship between the number of accidents, death toll and the level, region and time of accidents are analyzed. The results show that the relatively large accidents was the most among the coal and gas outburst accidents from 2010 to 2015, accounting for 68.42 percent of the total number, the death toll was also the largest, accounting for 45.68 percent of total deaths, the number of accidents and deaths was the most in Guizhou, the largest number of accidents occurred in August, coal and gas outburst accidents most likely occured before dawn.
