摘要

为了准确查明四川达竹煤电集团铁山南煤矿4013(26)回采工作面内隐伏煤层冲刷带的分布范围及展布特征,基于无线电波在矿井全空间的传播理论,探讨了无线电波坑透仪探测煤层冲刷带的可行性,并采用定点透视法进行了实际探测。结果表明,坑透技术对回采工作面内煤层冲刷带的分布规律及冲刷严重程度有很好的探测效果,结合区域地质资料分析,能较准确地划分出煤层受冲刷影响的灾害异常区,对工作面内构造特征进行预测预报,是一种理想可靠的探测工作面内煤层冲刷带的技术手段。
        In order to detect distribution range and expansion features of coal bed washout in 4013(26)working face of Tieshannan Mine of Sichuan Dazhu Coal Electricity Group,feasibility of detecting coal bed washout by radio wave penetration instrument was discussed and fixed- point perspective method was used on the basis of communication theory of radio wave in mine.The results showed that the technique had a good effect on distribution law of coal wash zone and severity of washing in working face.Combining with analysis of regional geological data,abnormal area caused by erosion in coal mine could be divided and structural features in working face could be predicted accurately,which was an ideal and reliable technological means to detect coal bed washout in working face.
