为了查明源兴煤矿上覆松散层厚度，防止发生溃矸溃水事故，改善矿井安全生产环境，本文采用高密度电法探测方法，对矿区指定范围进行探测。结果表明，探测范围内西部、西南部松散层厚度较大，最大厚度约为80 m左右，东部松散层厚度较小，东部、西北部部分存在基岩出露，基本查明矿区基岩面上覆松散层厚度。该技术为进一步提高矿井生产能力和技术水平，加强水害防治工作，煤矿安全生产提供技术保障。

 In order to find out the thickness of the overlying loose layer in Yuanxing Coal Mine, prevent the occurrence of gangue and water outburst accidents, and improve the safety production environment of the mine, this paper used high density electrical method to detect the specified range of the mining area. The results showed that the thickness of the loose layer in the west and southwest of the detection range was large, the maximum thickness was about 80 m, the thickness of the loose layer in the east was small, and the bedrock outcrops in the east and northwest. The thickness of the overlying loose layer on the bedrock surface of the mining area was basically identified. The study provided technical support for further improving mine production capacity and technical level, strengthening water disaster prevention and control work, and ensuring coal mine safety production.
