摘要
在对石嘴山一矿38区+600 m轨道巷围岩收敛变形和矿山压力进行现场监测的基础上,利用线性回归得到巷道表面相对移近速度,分析并总结了深部高应力软岩巷道矿压显现规律,对引起巷道破坏的主要原因进行探讨,并提出采用不对称的锚网索复合支护形式,为类似软岩巷道的支护设计提供科学依据。
Based on the distortion and the underground pressure at 38 panel 600 tracks lanes of Shizuishan Mine with the scene monitor in the foundation, use linear regression to get the surface relative speed of the entry, analyze and summarize the law of mine tension appearing at deep and high stress entry. It has also discussed main reasons of weak-soft entry breach, put forward the asymmetry compound support of blot-net-cable, supporting the design for the similar weak-soft entry to provide the scientific basis.
