摘要
针对司马矿二采区猴车巷里段部分区段巷道破坏严重的问题,设计新的中空注浆锚索支护方案进行改进补强支护,将原支护设计和改进支护方案设计进行比对,分析改进支护方案在各个时间节点的变化及原因。
Aiming at the problem of serious damage to monkey-car lane section of the second mining area section of the roadway in Sima mine, the new hollow grouting anchor cable support design for improving support is designed. By comparing the new hollow grouting anchor cable support design for improving support with the original support, the changes and reasons for improvement of supporting scheme in each time node are analysed.
