摘要

摘要: 为了探测煤层中的富水体,首次在新元矿区开展了基于广域电磁法的富水区探测,并同时配套了可控源音频大地电磁法作为对比。通过视电阻率数据曲线、频率—视电阻率拟断面图和反演结果的对比结果, 显示广域电磁法具有探测深度大、效率高、精度高的特点,可为煤矿富水区探测提供新的有效技术。

Abstract: To detect the water-rich areas in coal seams, the wide-field electromagnetic method (WFEM) was employed in the Xinyuan mining area of Huayang New Material Technology Group Co., Ltd. for the first time. Meanwhile, the controlled source audio-frequency magnetotellurics (CSAMT) was used for comparison. According to the comparison results of the apparent resistivity curves, frequency-apparent resistivity pseudo sections, and inversion results, WFEM enjoys the advantages of large detection depth, high efficiency, and high precision and thus serves as a new effective technology for the detection of water-rich areas in coal mines.
