摘　　要：高家庄煤矿掘进过程中,煤层的厚度变薄,并且出现无煤区,根据现场地质情况,初步判断为古河床冲刷带。针对这一问题,通过地质钻孔探测和地质素描相结合的方法,确定了冲刷带的空间位置分布,为巷道的顺利通过提供了可靠的地质依据,并实践验证了推断预测的准确性。通过对冲刷带的判断及探测研究,为揭露并处理冲刷带提供了成熟经验,也为矿井对于冲刷带的判断、探测及采取相应的处理措施提供一定的借鉴。During the excavation process of Gaojiazhuang Mine, the thickness of the coal seam became thinner and no coal area was encountered. According to the geological conditions, it was preliminarily judged to be the ancient riverbed scouring zone. In view of this problem, through the combination of geological drilling detection and geological sketching, the spatial position distribution of the erosion zone was determined, which provided a reliable geological basis for the smooth passage of the roadway, and the accuracy of the inference and prediction was verified in practice. Through the judgment and detection of the scouring zone, it provided mature experience for exposing and dealing with the scouring zone, and also provided certain reference for the judgment, detection and corresponding treatment measures of the scouring zone.
