摘　　要：为提高煤层工作面底板岩层赋水的探测精度,构建探测物理模型,采用并行直流电法技术对底板水害地质条件进行探测模拟实验,连续观测底板岩层含水条件变化时其电性剖面动态特征。结果表明,随着钻孔注水量的不断增加,低阻区域逐渐明显。该结果可以精确显示岩层不同深度赋水情况,为现场探测提供指导。This paper is an attempt to improve the detecting precision of the water-bearing strata of coal seam working face floor.The improvement research involves the development of detection physical model,simulation experiments on the geological conditions for water disasters occurring in coal seam working face floor using parallel direct current technology,and dynamic,real-time,and continuous observations of the electrical section features in the case of a change in water-bearing conditions of floor strata in.The results show that an increase in borehole water injection results in low resistivity zone becoming gradually obvious.The results,capable of accurately displaying the occurrence of water-bearing strata of different depths,may serve as a guide to the on-site detection.
