| 摘 要： | 通过瓦斯地质分析,提出煤层围岩透气性、断层复杂程度、褶皱变形复杂程度、煤层倾角复杂程度、顶板岩性、构造煤发育程度的量化方法和计算公式。采用因子分析方法对陶二煤矿2煤层影响瓦斯涌出的瓦斯地质指标进行筛选,确定出3个主因子,建立了瓦斯涌出量预测模型,经过理论和实践验证,模型精度较高,可以用于陶二矿未采区瓦斯涌出的预测。

| Abstract: | Based on gas geology analysis,the geological data qualification method and calculation formula of the permeability of wall rock of coal bed,the complex degree of fault,the complex degree of drape distortion,the complex degree of coal bed inclination angle,roof lithology and the development degree of tectonically deformed coals were put forward.The gas geology index affecting gas emission of No.2 coal bed in Taoer mine were screened out with factor analysis method and three major factors were identified,a prediction model of coal gas emission quantity was established.The theory and practice verifies that the model has higher precision,can is used in the forecast of gas emission in unmined area of Taoer mine. |
