钢管砼支架支护技术在软岩巷道维修中的应用分析

Application Analysis of Concrete-filled Steel Tube Bracket Support Technology in Soft Rock Roadway Maintenance

本文针对清水营煤矿受到软岩影响之后产生的巷道变形问题,在分析软岩性质之后来分析围岩应力和变化的规律,之后才能够提出合适的支护方案。本文在介绍完钢管支架的结构和工作原理之后全面地分析力学性能和施工的工艺。专业人员在分析完相关的施工工艺之后再有效地进行比较。为的是更好地体现出钢管砼支架在软岩巷道支护过程中的作用。

In this paper,aiming at the roadway deformation caused by soft rock in Qingshuiying Coal Mine,after analyzing the properties of soft rock,the stress and variation law of surrounding rock are analyzed,and then the appropriate supporting scheme can be put forward.After introducing the structure and working principle of steel pipe support,this paper comprehensively analyzes the mechanical properties and construction technology.After analyzing relevant construction techniques,professionals can effectively compare them,so as to better reflect the role of concretefilled steel tube bracket in soft rock roadway support.
