| 摘 要： | 针对陶二矿2煤层的瓦斯地质条件,借助数量化理论方法筛选出影响陶二矿2煤层瓦斯含量分布的因素为地质构造、顶板岩性、岩浆岩侵入、埋藏深度,采用线性回归模型预测各单元瓦斯沿走向和倾向分布规律,并将2煤层划分为3个瓦斯地质单元:Ⅰ单元为瓦斯风化带,Ⅱ单元为突出危险区,Ⅲ单元为潜在突出危险区。

| Abstract: | According to the gas geological conditions of No.2 seam in Taoer Mine,the quantification theory was applied to screen the factors affected to the gas content distribution of No.2 seam in Taoer Mine.The factors were the geological structures,roof lithology,magmatic rock intrusion and buried depth.The linear regression model was applied to predict the gas along strike and tendency distribution law of each unit.No.2 seam was divided into three gas geological units.Ⅰ unit was gas weathered zone,Ⅱ unit was outburst dangerous zone and Ⅲ unit was outburst dangerous zone in potential. |
