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。
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.
