In order to solve the problem that geological structures including collapse column,fault and so on had large number and large scale,which affected the safety mining of working face mining inside the No.090606 Face of Shanxi Shouyang Duanwang Coal Industry Group Co.,Ltd.,the pre-mining detection of geological structures such as collapse columns and faults in the working face was carried out by using the underground in-seam wave seismic exploration technology.Through the process of early indoor exploration design,mid-term field data collection,later data processing and result analysis,the location and influence range of geological structure(collapse column,fault,etc.)affecting mining in No.090606 Face were accurately delineated.According to the result report,effective measures were taken in advance for the mining work of the working face,which effectively reduced the risk caused by the hidden geological structure in the mining process of the working face,and achieved good economic and technical results.
