摘　　要： 由于煤层瓦斯分布的不均衡性,低瓦斯矿井中也有瓦斯较高的区域。特别是近年来,在一些低瓦斯矿井的瓦斯异常区也发生了一些重大瓦斯事故。对低瓦斯矿井的瓦斯异常问题,国内目前采取的办法往往只是加强通风、降低掘进速度等,很少有系统的防治方案,所以造成低瓦斯矿井也会发生瓦斯事故。针对付村煤矿瓦斯异常区综放工作面瓦斯源进行了分析研究,提出了有针对性的瓦斯综合治理方法。实践证明,采用几种形式结合的综合治理方法,可以达到治理瓦斯的目的,控制工作面的瓦斯浓度,确保瓦斯异常区的安全生产。 As coal gas distributes unbalance,there still has gas higher region on low-gas coal mine.Especially in recent years,there happened some major gas accidents in some low-gas coal mine at gas anomalous area.Aimed at the problems of gas anomalous,most coal mine settle it by strengthening the ventilation,reducing the speed of excavating and so on,so some major gas accidents still happens in the low-gas coal mine.This paper analyses and studies the sources of gas abnormal areas at Fucun Mine combined mining face and puts forward some corresponding gas control methods.Practice proves that by using several forms of comprehensive management methods,gas control can be realized and gas concentration on the combined mining face can be controlled,so safety in production at gas abnormal area can be achieved.
