地空电磁探测技术通过在地面布设电性源、空中无人机采集信号的工作方式，获取了探测区域的电磁响应数据，并分析其富水情况。煤矿地空电磁技术在山西古县老母坡矿老空水及含水构造探测，以及在冀中能源东庞矿西庞井区域治理注浆效果评价等方面得到了成功应用，对比水文地质资料，验证了探测技术的可行性与高效性，提前探明矿井的低阻异常区，为煤矿水害防治提供了技术依据。

 Ground-air electromagnetic detection technology obtained the electromagnetic response data of the detection area by laying electrical sources on the ground and collecting signals by aerial drones, and analyzed its water abundance situation. The ground-air electromagnetic technology of  coal mine was successfully applied in the detection of old goaf water and water-bearing structure in Laomupo Mine, Guxian County, Shanxi Province, and the evaluation of grouting effect in Xipangjing area of Jizhong Energy Dongpang Mine. Compared with hydrogeological data, the feasibility and efficiency of the detection technology were verified, and the low-resistance abnormal area of the mine was identified in advance, which provided a technical basis for the prevention and control of coal mine water disaster.
