摘　　要：杨村煤矿十采区10605工作面受底板承压双含水层的影响。为了查明底板双含水层的富水性,指导矿井防治水工作,在工作面上巷、下巷、切眼进行了底板瞬变电磁探测,获得了巷道断面图、底板不同深度含水层的水平切片图。探测成果表明底板十三-十四灰和奥灰的富水性不均一,呈现西部较强,东部较弱的特征。经验证,效果较好。为施工十三-十四灰疏水钻孔奠定了基础。The 10605 workface of the ten mining area in Yangcun coal mine is influenced by pressurized two-aquifers in floor. In order to i- denlify the water-richness of two-aquifer in floor and guide mine water prevention and control work, the mine transient electrnmagnefic detec- tion is done on the up laneway, down laneway and open-off cut. We get the cross-section diagram of the laneway and the horizontal section diagrams of aquifers in floors with different depth. Detection results demonstrate that the water-richness of the 13-14 limestone and Ordovi- clan limes/one is homogeneous and characterized by strong in the west and week in the east. The results are proven to work well and lay foun- dation for the construction of the 13-14 limestone hydrophobic drills.
