槽波透射勘探技术在综采工作面构造探测中的应用

Application of Groove Wave Transmission Exploration Technology in Structure Detection of Fully Mechanized Mining Face

为了查明晋能控股煤业集团寺河矿W2303工作面内部的地质异常情况,在工作面两侧顺槽及切眼分别布置了检波器,利用炸药作为震源,开展槽波透射勘探,提高了工作效率,确保了构造零误揭。分析了综采工作面构造探测中槽波透射勘探技术的应用,并结合后期回采过程中的异常点揭露情况进行了对比,提高了槽波勘探对小构造的解释精度。该技术的应用可为矿井安全生产提供保障。

In order to find out the geological abnormalities inside the W2303 working face of Sihe Coal Mine of Jinneng Holding Coal Industry Group,geophones were arranged along the groove and the cut hole on both sides of the working face,and the explosive was used as the seismic source to carry out groove wave transmission exploration,in order to improve the work efficiency and ensure that the structure exposing is zero mistakes.This paper analyzed the application of the groove wave transmission exploration technology in the structural detection of fully mechanized mining face,and compared the abnormal points revealed in the later stage of the mining process to improve the interpretation accuracy of the groove wave exploration for small structures.The application of this technology can provide guarantee for safe production in mines.
