|
摘要
为了长距离超前探测煤矿井下的地质构造情况,应用多波多分量地震勘探理论,介绍DTC-150井下长距离超前探测仪的基本原理,研究该仪器的井下测量方法与资料处理解释原则,并应用该仪器对不同的矿井进行超前预报探测实验。研究结果表明:采用DTC-150井下超前探测仪器能够较准确地探测到掘进面前方100m内断层、围岩裂隙、岩石破碎带以及富水情况,据由该仪器获得的波速对围岩进行分类。
In order to accurately detect the long-distance geological formation in front of the mine excavation work,the basic theory of the apparatus DTC-150 was introduced using multi-wave and multi-component seismic exploration theory.The measuring means and the data processing explanation principle of this apparatus,and the advanced forecast detection experiments were studied in allusion to different mines.The results show that advanced detection apparatus DTC-150 can detect geologic formation in front of the mine excavation 100 m away,and can more accurately detect faults,rock fissures,rock broken cinctures and water-rich situation,and the collection velocity can be used to classify the wall rock.
