高瓦斯矿井瓦斯治理措施研究

Study on Gas Control Measures in High Gas Mine

针对高瓦斯矿井作业环境内瓦斯超限的问题,以霍尔辛赫煤矿地质条件为背景,分析了矿井瓦斯赋存特征、通风现状以及瓦斯抽采现状,提出了从回采工作面瓦斯治理和掘进工作面瓦斯治理两方面做起,在不同的瓦斯含量区域采取不同的治理措施。现场瓦斯测定结果表明,所采取的瓦斯治理措施效果较好。

Aiming at the problem of gas overrun in the operating environment of high gas mine,based on the geological condi-tions of Huoerxinhe Coal Mine,this paper described the characteristics of mine gas occurrence,the status of ventilation and the current status of gas drainage,and proposed that different treatment schemes should be adopted in areas with different gas content in two aspects of gas control in mining face and excavation face.According to the on-site gas measurement results,the gas control measares have a good gas drainage effect.
