摘　　要：大倾角煤层的采空区问题是地质调查中存在的技术性难题.对中国新疆三塘湖鑫源煤矿采空区进行了研究,根据实际地质地形、岩性特征、煤矿露头走向、埋藏深度及采空区与围岩层之间存在的电性差异与其物理性质等条件,使用高密度电阻率法,针对地面150 m以浅范围内采空区分布及积水情况进行勘探,结果表明:该探测区内电性特征异常且分布复杂不均.采空区多呈现上覆岩层顶板部分下沉、岩层间破碎及断裂等特性,在空间位置上主要分布于治理区布控测线北侧,所处深度在30~80 m之间.通过钻探结果辅以验证,查明鑫源煤矿规划范围内采空区的大小范围、埋深情况及富水性等信息,证实高密度电阻率法用于探测倾角煤层中采空区的正确性与有效性.Steeply inclined coal seams mining often leads to the formation of goafs,which is a technical challenge in geological survey.In this study,the goaf of Xinyuan Coal Mine in Santanghu,Xinjiang of China was investigated.The high-density resistivity method was used to explore the distribution and water accumulation of the goaf within 150 m depth from the ground,which is based on the actual geological terrain,lithological characteristics,coal mine outcrop orientation,burial depth,the electrical differences and physical properties between the goaf and surrounding rock layers.The survey results showed that the electrical characteristics within the survey area were abnormal and distributed unevenly.The goaf mostly showed characteristics such as sinking of the overlying rock layers,fracture and fragmentation of rock layers.In terms of spatial location,it was mainly distributed on the northern side of the monitoring line in the control area and was located at a depth of 30»80 m.Through verification with drilling results,the size range,burial depth and water-richness of the goaf within the planned area of Xinyuan Coal Mine were confirmed.Additionally,the correctness and effectiveness of high-density resistivity method for detecting goaf in steeply inclined coal seams were verified.
