Abstract
To explore the geological structure characteristics and water bearing characteristics of collapse columns in Shiquan Coal Mine,Shanxi Province,using the CSAMT method,based on the eighth generation geophysical data acquisition system-System 2000.net geophysical system,the X1 and X3 collapse columns in Shiquan Coal Mine are detected.The research shows that the X1 collapse column mainly develops stone stacking section and mudstone slurry section,is a column wall small fault type karst collapse column,presents a relatively low resistance in the cross section,the column body is mainly a reflection of mudstone slurry.The X3 collapse column exhibits overall low resistance body in terms of electrical properties and belongs to the stone stacking and mudstone slurry type of karst collapse column.A relatively complete mudstone slurry section is developed inside the collapse column,which has a good barrier effect on phenomena such as water flow upwelling and others.The DX17 collapse column exhibits overall relatively high resistance in terms of electrical properties and belongs to the stone stacking debris type karst collapse column,its internal structure is relatively loose and has strong water conductivity.However,the karst aquifer of this type of collapse column generally has poor water richness,and the dangerousness of occuring water inrush accidents is relatively small.关键词
