软岩巷道支护实践应用

Practice and Application of Soft Rock Roadway Support

在布设软岩巷道的过程中,由于此类巷道的力学结构不够优良,在开展支护作业时存在较大的难度,需要在设计支护方案的基础上,对软岩的工程特征予以重点考虑,从力学特征、临界载荷与软化临界深度这三方面内容出发,对常见的软岩巷道支护设计方案进行探究。对软岩地质条件予以全方位的探讨,对最终的支护方式进行改善和升级,在全面改造巷道支护方式后,能够有效保障巷道的稳定性,促进相关施工作业顺利实施。

In the process of arranging soft rock roadway,because the mechanical structure of such roadway is not good enough,it is difficult to carry out the support operation,so it is necessary to focus on the engineering characteristics of soft rock based on the design of the support scheme,and explore the common soft rock roadway support design scheme from the three aspects of mechanical characteristics,critical load and softening critical depth.The geological conditions of soft rock are comprehensively discussed,and the final support mode is improved and upgraded.After the comprehensive transformation of the roadway support mode,the stability of the roadway can be effectively guaranteed,and the smooth implementation of relevant construction operations can be promoted.
