| 摘 要： | 位于焦作矿区东南部的赵固一矿因岩溶裂隙水患、基岩厚度薄和新生界盖层厚等三大因素制约了开采而长期搁置.在以往勘探成果基础上,利用大口径群孔抽水试验成果资料,对矿区边界条件、岩溶水的连通性、水动力特征、和水化学特征等诸方面进行了分析,通过评价认为处在二1煤底板的L8岩溶含水层富水程度中等,其二1煤层可以开采,较客观地认识了水患问题.

| Abstract: | Because of karstic fissure mine water disaster as well as thin bedrock cover strata and thick Cenozoic overburden three major factors, the Zhaogu No.1 coalmine in the southeastern part of Jiaozuo mining area has left aside over a long period of time. On the basis of former exploration results, and use large-diameter multiple-well pumping test results, the paper analyzed mining area boundary condition, karstic water connectivity, hydrodynamic, hydrochemical features considered that the L8 karstic aquifer under the No.21 coal floor has medium water abundance, thus No.21 coal there is mineable, rather objectively assessed the mine water disaster. |
