摘要
双庙扩大区-600水平轨道地质条件较差,采用一般支护方式无法保证巷道的稳定性,决定结合及时观测、采用让压锚注施工二次支护方式对巷道进行施工。通过现场监测,让压与锚注施工技术在双庙扩大区获得了成功,达到了支护巷道的目的,解决了葛店煤矿高地压下软岩巷道支护困难的问题。
The geological condition of -600 horizontla tunnel of Ge-dian mining is bad, it can＇t guarantee the stability of tunnel when using general support ways, combining in time observing, we use yield and shotcrete technology in support schemes. Which is succeed in resisting runnel deformation and ensure the ability of produce, achieving the goal of control the deformation of tunnel, solving the difficult question of support in the condition of soft rock and high textural stress.
