| 摘 要： | 宋楼煤矿主斜井在掘进过程中涌水淹井,根据该区的地质背景及地球物理特征,决定采用直流电法进行勘探,以查明突水原因,圈定水源.从电法主测线断面上看,横向视电阻率值在250m处变化较大,与实际矿井涌水位置相吻合,据此圈定其余3个富水区.另外利用反演软件定量解释了目的层的深度、厚度及电阻率值.

| Abstract: | A mine flooding accident was happened in main slant of Songlou coalmine during road heading,based on the area's geological background and geophysical features,decided to use direct current prospecting to find out the causation of the flooding and block out water source.Transverse apparent resistivity has a fair-sized changing at 250m on the in-line and tally with actual water inflow position,thus to block out another 3 water abundant zones.In addition,by the use of inversion software interpreted target area depth,thickness and resistivity quantitatively. |
