摘要
为解决华阳集团平舒公司15302综采工作面过陷落柱X160问题,采用数值模拟研究,结合现场工程情况,对陷落柱影响区域进行超前注浆改造。治理措施实施完成后,回采期间对15302工作面127个液压支架进行应力观测,支架应力波动范围为260~270 kPa。
In order to solve the problem that the 15302 fully mechanized mining face of Pingshu Company of Huayang Group passes through the collapse column X160,the numerical simulation study is adopted,and the area affected by the collapse column is advanced grouting and transformation combined with the site engineering conditions.After the implementation of the control measures,the stress of 127 hydraulic supports in the 15302 working face is observed during mining period,and the stress fluctuation range of the support is 260-270 kPa.
