摘要
陷落柱是煤矿建设和生产中经常遇到的地质因素之一,通过研究陷落柱的构造特性,根据具体工程的实际情况,运用理论分析计算和数值模拟手段,对比论证,确定陷落柱加固的处理部位与范围以及工作面通过陷落柱的工程措施,经工程验证,现已安全通过。
The collapse column is one of the geological factors affecting coal mine production and eonstruetion, by studying the characteristics of the structure of the collapsing column and mechanical mechanism of the influence on the roof and floor, according to the actual eireum stance of working face, through the theoretical analysis and calculation, numerical simulation methods, multiple comparison, to determine the collapse column reinforcement processing parts and scope as well as the working face through engineering measures of collapse column, it has been verified by engineering, safer now. ｜
