摘　　要：本文根据直接推过、绕过陷落柱所产生的工程费用进行分析,建立了过陷落柱方案的比较方程;采用模糊数学综合评价的方法,对中煤平朔集团井工一矿X5和X7陷落柱进行模糊评价,并确定X5和X7陷落柱的通过方案。根据颗粒极配实验和岩土介质渗透实验结果,确定陷落柱内部需要化学浆加固,施工中采用了超前深孔注水泥水玻璃与架前注化学浆相结合的方式进行加固,取得较好效果。According to engineering cost of push through the collapse column and Bypass the collapse column, established comparison equation of Choosing collapse column scheme; Adopted fuzzy mathematics comprehensive evaluation method,Evaluated X5 and X7 collapse column in Pingshuo Coal Industry Company No. 1 Coal Mine, ultimately determined using the scheme of pushing through X5 and X7 collapse column. According to the result of particle distribution experiment and rock and soil permeability Experiment, determined rock and soil in the collapse column is weak water permeability, need to use chemical grouting reinforcement ; Actually, used 2 schemes is Pre - deep hole cementing water glass and injection of chemical pulp in the front of Hydraulic support to reinforce.
