| 摘 要： | 运用板块构造理论和区域地质演化理论,研究了磴槽煤矿所在的登封矿区地质构造演化及分布特征,并结合磴槽煤矿的大量瓦斯地质资料和瓦斯测试参数,分析了矿井瓦斯地质规律、赋存规律.受豫西滑动构造的影响,磴槽煤矿二1煤层成层发育构造煤,构造煤的放散初速度高、比表面积高、强度低、透气性低,这造成了钻孔瓦斯涌出初速度值达不到<防治煤与瓦斯突出细则>规定的临界值,因而导致瓦斯突出的发生.

| Abstract: | With the plate tectonics theory and the area geological evolution theory,the paper studied the geological tectonic evolution and distribution features in Dengfeng Mining Area of Dengcao Mine.In combined with the great gas geological information and gas measured parameters of Dengcao Mine,the paper analyzed the mine gas geological law,deposit law and the influences of the Yuxi sliding tectonics.The B1 seam in Dengcao Mine was a well developed tectonic coal with a high releasing viscosity,high surface ratio,l... |
