瓦斯综合防治方法研究

Research of Integrated Method of Prevention and Control of Gas

统计分析了煤矿瓦斯事故中死亡人数占煤矿事故死亡人数的比例:我国一次死亡10人以上重特大瓦斯事故死亡人数占69.5%,一次死亡百人以上重特大瓦斯事故死亡人数占65.4%,国外一次死亡30人以上重特大瓦斯事故死亡人数占95.3%;分析了瓦斯事故发生的原因,指出瓦斯爆炸事故是可以避免的,进而提出了通风、监控、抽采(抽放)、供电、防爆、防尘、防火、爆破、避险等综合防治瓦斯的方法,并阐述了煤矿安全监控系统在瓦斯防治中的作用。

The paper analyzed ratios between death toll in mine gas accidents and death toll in mine disasters, namely ratio is 69.5% between death toll in serious gas accidents in which death toll is over 10 and death toll in mine disasters and ratio is 65.4% between death toll in serious gas accidents in which death toll is over 100 and death toll in mine disasters in our country, and overseas ratio is 95.3% between death toll in serious gas accidents in which death toll is over 30 and death toll in mine disasters. It analyzed causes of gas accident, pointed out gas explosion accidents can be avoided, put forward integrated method of prevention and control of gas such as ventilation, monitoring and control, gas extraction （drainage）, power supply, explosion-proof, dust-proof, fire-proof, blasting and act of rescue, and expounded effect of coal mine safety monitoring and control system in preventing gas.
