摘要
底板岩层压水试验能够获得可靠的底板岩层阻水能力实测数据,为深部煤层开采底板岩层阻水能力提供量化依据,对东滩煤矿深部煤层底板岩层进行压水测试,获得了大量的实测数据并依此计算出岩层的渗透系数。试验结果表明测试底板岩层段在原始状态下的渗透性很低,阻水能力较强。研究结果可为矿区深部工作面的安全开采提供重要的参考依据。
The reliable reduction infiltration characteristics of rock mass could be obtained by the water injection experiment under the coal seem floor. The data of water injection experimnt were obtained and permeability coefficient of floor formation were deduced through water in- jection experiment at Dongtan Coal Mine. Result shows that the test rock formations are all low-permeability, which mean they have high re- duction infiltration ability. The results make a important reference for safety-mining of deep coal seam working face.
