为了改善矿井安全生产环境，进一步提高矿井生产能力和技术水平，加强水害防治工作，根据煤矿生产建设和安全的需要，利用地空电磁法勘探技术探测效率高、成本低、对良导电解质响应敏感等优势，对山西寿阳段王煤业集团有限公司八采区内的主要可采煤层采空区积水情况进行探查。通过前期室内勘探设计，中期现场数据采集，后期数据处理、成果分析等过程，较好的完成了此次地空电磁探测任务。根据探测结果，共圈定5处疑似采空积水区。经过对其中3号、4号两处异常区打钻验证，结果表明2处异常区均为8+9号煤层采空积水区域，且平面投影形态及影响范围与地面探测成果圈定的情况一致度较高，研究结果充分说明了地空电磁勘探技术在段王矿采空积水区探测中的可行性及有效性，最大限度的降低了八采区后期掘进、回采过程中所面临的水文地质方面的风险，取得了较好的经济技术价值。

 In order to improve the mine safety production environment, further improve the mine production capacity and technical level, and strengthen the prevention and control of water disasters, according to the needs of coal mine production construction and safety, the ground-air electromagnetic exploration technology was used to detect the water accumulation in the goaf of the main minable coal seam in No.8 mining area of Shanxi Shouyang Duanwang Coal Industry Group Co., Ltd., with the advantages of high detection efficiency, low cost and sensitive response to good conductive electrolyte. Through the early indoor exploration design, mid-term field data acquisition, post-data processing, result analysis and other processes, the ground-air electromagnetic exploration task was well completed. According to the detection results, a total of 5 suspected goaf water accumulation areas were delineated. After drilling and verifying the two abnormal areas of No.3 and No.4, the results showed that the two abnormal areas were the goaf water accumulation areas of No.8 + 9 coal seam, and the plane projection form and influence range were highly consistent with the delineation of ground detection results. The research results fully demonstrated the feasibility and effectiveness of ground-air electromagnetic exploration technology in the detection of goaf water accumulation area in Duanwang Mine. And ground-air electromagnetic exploration minimized the hydrogeological risks faced in the later excavation and mining process of No.8 mining area, which achieved good economic and technical value.
