摘要
阐述了瓦斯生成原理及爆炸的原因,基于瓦斯地质学,对瓦斯地质规律进行分析,了解瓦斯在煤层中赋存情况与地质概况。阐述了瓦斯抽放相关技术,并对两种抽采方式效果进行比较分析。在寺家庄矿实践表明,巷道内的瓦斯含量控制在安全可控范围,保障了工作面的采掘进度。
The generation principle and the explosion reason of gas was expounded, based on gas geology, the gas geology law was analyzed, the occurrence and geology condition of gas in coal seam was got. The relative technology of gas drainage was explained, the two ways of the drainage was analyzed and compared. The practice in Sijiazhuang Mine showed that the gas content in roadway was safe and under control, which ensured the mining speed.
