摘要
采用EH-4连续电导率剖面仪对工作面陷落柱附近区域进行监测,分析陷落柱及其两侧所表现的电阻率特性,第四系下组含水地层和3下煤层顶板含水地层的富水程度与陷落柱的存在具有明显的相关性,陷落柱及其顶部的含水岩层富水性相对较强,而其两侧的含水岩层的富水性相对较弱。
By carrying out the exploration the vicinity of the collapse column using EH-4 continuous conductivity profile instrument, and analyze the resistivity characteristics of the collapse column and on both sides of the performance, the result show that the water storage capacity has obvious relevance between the Quaternary group aquifer layer and 3 coal seam roof aquifer strata with the collapse column, the water storage capacity of the collapse column and the upper beating water rock layer is relatively strong, but is relatively weak in both sides of the collapse column.
