古山立井西二采区运输石门施工中遇到了复杂的软岩问题 ,工程受阻。通过分析 ,找出了软岩巷道难支护的本质原因 ,即具有复杂的变形力学机制。施工中采取合理的支护对策对其进行转化 ,取得了良好的支护效果 ,并实现了一次成巷。
The construction of Shimen in the second mining area in the west of Gushanlijing encountered complex soft rock problems and the project was blocked. Through the analysis, the essential reason of soft rock roadway support is found out, that is to say, it has complicated mechanism of deformation mechanics. In the course of construction, reasonable support measures are taken to transform them and a good supporting effect has been achieved and an alley has been realized.
