摘　　要：为减少煤矿采空区安全事故的发生,提高采空区内部构造探测精准度,对高精度重力测量在煤矿采空区探测中的应用进行研究,对研究地区布设重力测量剖面。在此基础上,设计反演采空区模型,在反演过程中,分析煤矿采空区结构,通过欧拉反褶积原理,对重力测量出的异常数据进行计算处理,确定煤矿采空区的位置、深度以及分布范围。通过实验论证,确定该应用的合理性,证明了该方法在探测工作中的优越性。In order to reduce the occurrence of safety accidents in coal mine goaf and improve the accuracy of internal structure detection in goaf,the application of high-precision gravity survey in coal mine goaf detection is studied,and gravity survey profiles are arranged in the study area.On this basis,the inversion goaf model is designed.In the process of inversion,the structure of coal mine goaf is analyzed,and the abnormal data measured by gravity are calculated and processed by Euler deconvolution principle,determine the location,depth and distribution range of the coal mine goaf.Through experimental demonstration,the rationality of the application is determined,and the superiority of this method in detection work is proved.
