摘要
煤层瓦斯质量体积(含量)是煤层瓦斯主要参数之一,是矿井进行瓦斯涌出量预测、煤与瓦斯突出预测和瓦斯抽放设计的重要依据.只有摸清矿井瓦斯赋存规律,才能对采掘面瓦斯抽放制定合理的技术措施.为避免石门沟煤矿瓦斯治理的盲目性,笔者通过分析煤层瓦斯质量体积与埋藏深度的关系,并结合矿井地质构造,研究了煤层瓦斯赋存规律,总结得出石门沟煤矿3号煤层瓦斯质量体积受地质构造控制,在远离地质构造区域,瓦斯质量体积与埋藏深度呈正相关,并推出其关系式,为矿井瓦斯治理提供可靠数据.
Coal seam gas content is one of the main parameters of coal seam, which is the important basis for the forecast of mine gas emission, coal and gas outburst, and design of gas drainage. There will be a pointed governing measure on digging face and mind face, only by finding out the methane occurrence law in order to avoid the blindness of Shimengou mine gas governs. The author analysises relations between the gas content of coal seam and burial depth, and combines the geological structure of the mine, study coal bed gas tax. The paper draws that coal seam gas content tax is controlled by the geological structure, when far away from the geological structure area, the content of gas is correlated with burying depth and put out the relational expression, which offers the reliable data for the mine gas controling.
