摘要
陷落柱区域富水性的探测研究对预防矿井水害有重要意义。根据大阳煤矿井田钻探资料、地质信息等,对煤矿的充水因素进行分析,采用地面瞬变电磁法和井下探测相结合的探查技术对其采区内XT1陷落柱的富水性进行了探查研究,并提出相应的防治水对策建议。在测区内通过在距3~#煤顶30 m,3~#煤,3~#煤底30 m,9~#煤,15~#煤,15~#煤底30 m的不同层位做了六张视电阻率水平切片,对不同水平截面瞬变电磁切片分析,推测测区内异常区情况。结果表明:XT1陷落柱为弱富水性,含水层位为3~#煤层底30 m、9~#煤层和15~#煤层。
The investigation of the water abundance in the subsided column area is of great importance to prevent mine water damage.According to the drilling data and geological information of Dayang Coal Mine,the water filling factors of coal mine is analyzed,the water-richness of collapse colume XT1 is explored in the mining area,using the combination of ground transient electromagnetic and underground detection,and the corresponding countermeasures and suggestions on the prevention and control of water is put forward.In the test area through the 3# from the top coal 30 m,3# coal,3# coal base 30 m,9# coal,15# coal,15# coal 30 m in different layers of bottom made six resistivity horizontal slice,transient electromagnetic analysis of different sections of horizontal section that measured transient,abnormal region.The results show that the XT1 collapse column is weakly rich in water,the aquifer is 3#,the coal seam bottom is 30 m,9#coal seam and 15#coal seam.
