摘　　要：为保证何家塔煤矿501盘区50106工作面的安全开采,利用无线电波透视法探测50106工作面、其上部异常地质构造及其含水层富水性的垂向及平面分布,为该工作面的防治水设计提供地质依据以及技术支撑。基于50106工作无线电波透视探测反演的实测场强曲线图、实测场强分布图和SIRT反演吸收系数(CT成像)图共同圈定了工作面内3处异常范围分布,推断YC01(850~1000m)、YC02(1300~1900m)和YC03(2950~3970m)异常为冲刷带导致煤层变薄引起的。巷道掘进地质资料表明,YC01和YC02异常所在位置无断层等构造反映。研究表明,采用无线电波透视法可以较好地揭示回采工作面地质构造及其上部顶板不同深度范围的电性异常特征,是保障矿井工作面安全高效生产的有效技术。In order to ensure the safe mining of 50106 working face in 501 block of Hejiata Coal Mine,radio wave perspective method was used to detect the abnormal geological structure of 50106 working face and its upper part as well as the vertical and plane distribution of water-rich aquifer,which provides geological basis and technical support for the water control design of this working face.Based on the measured field strength curve,the measured field strength distribution diagram and the SIRT inversion absorption coefficient(CT imaging)of radio wave perspective detection inversion in 50106 work,the three abnormal range distributions in the working face were delineated.It was inferred that YC01(850-1000 m),YC02(1300-1900 m)and YC03(2950-3970 m)were caused by the thinning of the coal seam caused by the scouring zone.The research shows that the radio wave perspective method can better reveal the geological structure of the mining face and the electrical anomaly characteristics of the upper roof at different depths,and is an effective technology to ensure the safe and efficient production of the mine working face.
