马泰壕煤矿3-1煤层瓦斯地质规律与瓦斯预测

Gas-geology Law and Gas Forecast of 3-1 Coal Seam in Mataihao Coal Mine

在收集整理马泰壕煤矿地质资料和瓦斯资料的基础上,运用瓦斯地质理论和构造演化理论,分析井田地质构造演化及分布特征,研究地质构造、顶底板岩性、煤层赋存状态等地质因素对瓦斯赋存的影响。在此基础上,结合现场测定3-1煤层瓦斯含量等参数,得出了矿井3-1煤层瓦斯地质规律。研究结果表明,煤层埋藏深度是影响马泰壕煤矿3-1煤层瓦斯的主控因素。

Based on the collection of geological data and gas data which come from Mataihao Coal Mine,the theory of gas geology and tectonic evolution were used to analyse the tectonic evolution and distribution characteristics of coal mine,the influence on the geological factors were also studied,including geological structure,coal seam roof and floor lithology,coal seam occurrence state and so on. On this basis,combined with field measurement of 3-1 coal seam gas content and other parameters,laws of 3-1 coal mine gas-geology were obtained. The research results show that,the burial depth of coal seam is the main control factor of 3-1 coal seam gas in Mataihao Coal Mine.
