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。

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 C ontent distribution of No.2 seam in TaoDer Mine.The factors were the geological structures, roof lithology, magmatic rock intrusion and buried depth. The linear regressio n 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 we athered zone, I unit was outburst dangerous zone and unit was outburst dangerous zone in potential.
