摘　　要：利用直流电法仪探查原采空区的积水情况,既解除掘进过程中受老空水的威胁,又避免钻探。介绍了该仪器工作原理和在实际探测中的应用,经实际揭露情况和仪器探测的结果基本吻合,为安全生产和经济效益的提高奠定了基础。The use of direct current instrument exploration of water mined - out area of the original case, both lift the tunneling process by the old empty threat of water, but also to avoid drilling. Describes the working principle of the instrument and the actual detection of the application, by exposing the real situation and basically consistent with the results of detecting devices for the safe production and laid the foundation for the improvement of economic effieiency.
