摘要
为解决煤矿井下独头巷道超前探测问题,对层状介质下钻孔内供电、接收工作模式三维直流超前探测模型,采用有限单元法进行了数值模拟。结果表明,钻孔内供电并接收,极大提高了异常幅度,简化了视电阻率曲线与异常的对应关系,极大提高了对未知致灾隐患的探查能力。
In order to solve the coal mine advanced detection problem in roadway,the layered media simulation under the power supply and receiving in the borehole was carried out by the finite element method in this paper.The simulation results show that the power supply and received inside the hole greatly improve the abnormal amplitude,simplifies the corresponding relationship between the apparent resistivity curve and abnormal,greatly improve the ability of detection to the unknown danger.
