本文介绍了井下煤层底板岩层水力学特性（含单位涌水量、水压、渗透系数、裂隙导高带等）的钻孔原位测试方法，以太原市东山煤矿为例，详细给出了煤层底板石炭纪太原组和本溪组岩层的含水性态（水压、单位涌水量、渗透系数）及其奥灰水裂隙导高带等测试方法和结果，对承压水上采煤问题具有重要的参考价值。
This paper introduces the drilling in situ testing method of hydraulic characteristics (including unit water inflow, hydraulic pressure, permeability coefficient, fractured guide belt and so on) of rock strata of underground coal seam. Taking Dongshan Coal Mine in Taiyuan as an example, The test methods and results of the water quality (water pressure, unit inflow, permeability coefficient) of the rocks in the Carboniferous Taiyuan Formation and the Benxi Formation and their lead-induced gray water fracture zone have important reference values for the problem of coal mining on confined water .
