软岩巷道设计施工中应注意的问题分析

Analysis of problems in design and construction of soft rock roadway

随着我国经济发展水平的不断提高,矿山开采技术水平得到了显著提高,开采的深度在不断增加。在这种情况下,巷道围岩会出现变形,再加上支护技术水平的限制,生产将面临阻碍。使用传统的岩石力学方法对巷道设计进行计算、施工也不能充分满足生产需求。为此,使用综合软岩矿井开拓方法以及科学的巷道布置方法,并合理选择支护技术材料、做好断面判断至关重要。主要对软岩巷道设计施工中常遇到的问题进行了分析,并提出了几点技术上的优化方法,希望能够为相关部门提供一些借鉴。

With the continuous improvement of Chinese economic development,the level of mining technology has been significantly improved,the depth of mining is increasing.In this case,the surrounding rock will be deformed,coupled with the level of the technical level of support,production will be faced with obstacles.Using the traditional rock mechanics method to calculate the roadway design and construction can not fully meet the production needs.To this end,the use of comprehensive soft rock mine development methods and the scientific approach to the layout of the roadway,and reasonable choice of supporting technical materials,agood section judgment are necessarily important.The main problems in soft rock roadway design and construction are analyzed,and some optimization methods are put forward,hoping to provide some reference for the relevant departments.
