杨柳煤矿瓦斯防治分析

Analysis on Gas Prevention and Control in Yangliu Coal Mine

瓦斯事故是煤矿开采过程中发生的严重自然灾害之一,在特大煤矿事故中占很大比例,所以搞好瓦斯防治是至关重要;简要介绍了本矿地质构造情况,分析了瓦斯分布以及影响瓦斯含量的各种影响因素,本矿安全生产面临着严峻形势,为了能够降低瓦斯含量,消除隐患,实现安全生产;重点介绍了煤矿瓦斯防治的技术手段,其包括顺层钻孔抽放,斜交钻孔,高位走向钻孔,向上拦截钻孔以及埋管抽放技术在本矿中的具体应用。

Gas accident is one of the serious natural disasters that occur in the coal mining process, es-pecially in extraordinary serious coal mine accidents, so improving gas prevention is crucial. This paper makes a brief analysis on the geological structure of Yangliu Coal Mine and analyzes gas distribution and various factors affecting the gas content of the mine. Then the safety in production is facing grim situa tion. In order to reduce the gas content, eliminate hidden dangers, and realize the safety in production, this paper focuses on gas prevention and control techniques of the coal mine, including drilling drainage of the bedding, bias drilling, high toward drilling and pipe drainage technology , and specific applications.
