根据火烧区煤岩层中富水岩性的不同地质特征,采用瞬变电磁法对火烧区煤岩回采工作面顶板进行探测,结合井下的地质资料判断是否出现富水区域。结果表明,矿井瞬变电磁法能有效圈定出火烧区下伏煤层工作面顶板富水性的位置和范围,探测结果与钻探验证结果基本吻合,为煤矿安全生产提供技术依据。
According to the different geologic characteristics of the water-rich lithology in the coal seam in the fire zone, the roof of the coal mining face in the fire zone is detected by the transient electromagnetic method. Whether the water-rich zone appears is determined by the geological data of the well. The results show that the mine transient electromagnetic method can effectively delineate the position and the range of the water-rich roof of the coal seam in the fire area. The results of the exploration are in good agreement with the results of the drilling verification, providing the technical basis for coal mine safety production.
