软岩巷道的破坏机理与控制

Destruction Mechanism and Control of Soft Rock Roadways

在工程实践中,巷道施工发生变形破坏的现象十分常见,尤其是在深井软岩巷道中更为频繁和突出。越来越深的采深,采动压力以及越来越复杂的围岩地质情况,不仅加大了挖掘难度,而且为巷道安全质量带来了十分大的隐患,为确保巷道环境安全稳定,专家学者们也做了大量研究,几十年来也取得了丰硕的成果。本文主要介绍了一些常见的软岩巷道破坏机理和工程常用支护和控制稳定的方法,在保证巷道环境安全稳定的前提下选择最合理的施工方法,满足井下设备基础正常使用,减少二次支护合理降低造价。

In the engineering practice, deformation and destruction of roadway the phenomenon of construction is very common, especially in the soft rock tunnels of deep wells. Deeper and deeper mining, mining pressure and complex geological conditions of the sun＇ounding rock not only increase the difficulty of digging, but also bring great bidden dangers to the safety and quality of the roadway. In order to ensure the safety and stability of the roadway environment, experts and scholars We have also done a lot of research and achieved fruitful results for decades. This article mainly introduces some common soft rock roadway failure mechanisms and the methods commonly used for supporting and controlling the stability of the road. Under the premise of ensuring the safety and stability of the roadway environment,the most reasonable construction method is selected to meet the normal use of thedownhole equipment foundation and reduce the secondary branch. Safeguarding reasonable cost reductions.
