矿井综合物探方法在工作面掘进至陷落柱精细探测中的应用

Application of Comprehensive Geophysical Prospecting Method in Fine Detection When Mining Face Advancing to Collapse Columns

本文在研究伯方矿陷落柱地质特征的基础上,在井下采用三点-三极和瞬变电磁两种物探手段,在掘进头对陷落柱进行超前探测。通过不同的方法进行综合探查和解释,准确地圈定出掘进头陷落柱的范围,为陷落柱的探查提供了新的思路和方法。结果表明:该综合物探探测结果与巷道实际揭露情况一致,有效指导了掘进工作面的设计与施工。

Based on the study of the geological characteristics of collapse columns in Bofang mine,two geophysical methods,three-point-three-pole and transient electromagnetic,are adopted underground in the advance detection of the collapse columns.Through different methods of comprehensive exploration and interpretation,the range of the collapse columns at the head is accurately determined,which provides a new idea for the exploration.The results show that the comprehensive geophysical prospecting results are consistent with the actual roadway exposure,which could effectively guide the design and construction of the working face.
