摘要
岳城煤矿拟开采的石炭系太原组中下部15号煤层,存在承压开采问题。采用定量与定性分析相结合的方法,以含水层富水性、隔水层隔水性、断裂构造发育程度及导水性为主要指标,评价了承压开采安全性,并提出了相应的防治水技术措施,可为15号煤层开采提供科学依据。
No. 15 coal seam which is to be mined in Yuecheng Coal Mine is in the middle and bottom of the Carboniferous Taiyuan formation, and it belongs to pressure-bearing mining. Combined with qualitative and quantitative analysis, taking water abundance of aquifer,impermeability of aquiclude,development degree and transmissibility of fracture structure as the main indexes,the security of pressure-bearing mining was also evaluated,the prevention measures were put forward which has provided a scientific basis for No. 15 coal seam.
