采煤工作面上隅角瓦斯治理分析与应用

Analysis and Application of the Upper Corner Gas Control on Coal Face

在采用"U"型通风的采煤工作面,上隅角极易发生瓦斯超限及瓦斯积聚事故。本文针对铁新煤矿实际情况,以9104工作面为例,从瓦斯的来源、矿压、地质构造等影响因素方面进行分析,总结了矿井瓦斯赋存规律和具体治理措施,并应用到生产实践,取得了良好的效果。

In the use of "U" type ventilation in the coal mining face, the upper corner prone to accumulate disallowed gas concentration and gas accident. In this paper, according to the actual situation of Tiexin Coal Mine, taking the 9104 working face as an example, carries on the analysis from the aspects of factors affecting gas sources, mine pressure, geological structure, summarizes the mine gas occurrence regularity and concrete measures, and applied to practical production, has received the good effect.
