    摘要:

    为实现金谷煤矿小煤窑采掘边界圈定,采用地空频率域电磁系统开展小煤窑采空积水区的勘查试验工作。实际勘探中设计124条南北方向测线,利用无人机搭载探测天线进行电磁数据的连续采集。通过数据处理与解释,获得了测区内地下50~300 m范围内的视电阻率剖面。根据相对低阻异常的分布情况,圈围出两个煤窑采空积水区疑似位置。经过与实际煤层采掘资料对比,圈定的1处低阻异常区域下方存在高度充水的采空区。研究结果证明了地空频率域电磁系统在小煤窑勘查工作中的可行性及有效性。

    Abstract:

    In order to realize the boundary delineation of small coal mines in Jingu Coal Mine, the ground airborne frequency domain electromagnetic system is used to carry out for the survey and test work of the small coal mine goafs. In the actual exploration, 124 survey lines in the north-south direction were designed, and the UAV equipped with the detection antenna was used to continuously collect the electromagnetic data. Through data processing and interpretation, the apparent resistivity structure drawing within the range of -50~-300 m underground in the survey area is obtained. According to the relatively low-resistance anomaly distribution, the suspected locations of the two coal mine goaf areas are demarcated. After comparing with the actual coal mining data, there is a goaf with high water filling under the two defined low resistance abnormal areas. The research results prove the feasibility and effectiveness of the ground airborne frequency domain electromagnetic system in the investigation of small coal mines.
