综合孔中物探技术在长距离定向钻孔精细探查中的应用
Application of comprehensive borehole geophysical exploration technology in fine exploration of long-distance directional drilling
摘要
Abstract
Due to the development of rapid excavation technology in coal mine roadway,conventional advanced geophysical methods have been greatly affected,the"short excavation and short detection"technology can't meet the current technical requirements of long-distance and high-precision geological advanced detection.In response to these problems,this article proposes the use of a comprehensive borehole geophysical exploration method in the long-distance directional drilling of the roof track roadway that has been constructed.The transient electromagnetic method in the borehole is primarily used to detect abnormal water-rich areas near the borehole.Using three-component data positioning technology,three-dimensional imaging of transient electromagnetic detection results in holes is performed,allowing for the spatial distribution of abnormal water-rich areas to be analyzed.The borehole geological radar technology can be used to explore the geological structure near the borehole trajectory.According to the time domain response profile of the borehole geological radar,the change in form and missing position of the reflected signal in the in-phase axis are analyzed,and the structural characteristics are identified.These two geophysical prospecting methods are mutually verified and interpreted,thus revealing the geological attributes of abnormal bodies.The results of underground practice show that the comprehensive use of the borehole geophysical prospecting method can reduce the multi-solution problem of a single method,improve the accuracy of exploration and identification of hidden geological anomalies,effectively reflect the structures such as faults with small drops near the borehole,and realize the fine exploration of geological anomalies near the borehole trajectory.关键词
