为探究山西省石泉煤矿陷落柱地质结构特征与含水性特征,采用CSAMT方法,基于第八代地球物理数据采集系统-System2000.net地球物理系统,探测了石泉煤矿X1与X3陷落柱。研究表明:X1陷落柱主要发育了堆石段和泥石浆段,为柱壁小断层型岩溶陷落柱,在断面呈现相对低阻,柱体主要为泥石浆的反映。X3陷落柱在电性上整体表现为低阻体,属于堆石泥石浆型岩溶陷落柱。该陷落柱内已发育有较为完整的泥石浆段,对水流上涌等现象具有良好的阻隔作用。DX17陷落柱在电性上整体呈现相对高阻,属于堆石碎屑型岩溶陷落柱,其内部结构较为松散,具有很强的导水性,但该种类陷落柱的岩溶含水层一般具有较差的富水性。该陷落柱发生突水事故的危险性较小。

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.
