Abstract

The X5 collapse column encountered in the mining of 30107 working face in Shiquan coal mine was geophysical explored by multi-electrode resistivity method. Combined with the inversion of mine multi-electrode resistivity method, the resistivity response characteristics are analyzed and explained in detail, and the geological structure characteristics of collapse column are obtained. It is found that the decisive factor of water inrush of collapse column is mud section. The geophysical exploration results show that there is a mud section with complete cementation and dense compaction 0 ~ 100m below the trench floor of 30107 belt roadway, which is the water resisting layer of the confined water mining floor of No. 3 coal seam, The existence of mud section ensures the safe mining of the working face. The geophysical exploration results have reference significance for the collapse columns with obvious segmentation of similar geological structures.
