采场巷道围岩变形宏观规律的监测和分析

The Measurement and Analysis of Macroscopic Deformation Rules for Wall Rock of Stope Drift

通过对小官庄铁矿破裂岩巷道表面的深部位移十多年的现场实测 ,总结了破碎岩锚杆支护巷道围岩的宏观变形特征 。

Based on the analysis of the ongoing engineering practice of fractured rock in Xiaoguanzhuang iron mine for ten years,the characteristic of macroscopic deformation of surrounding rock of stope drift is researched.The research has great important real practical significance to study on the deformation mechanisms and the support techniques.
