摘要
本文系统地总结了我国煤矿巷道在软岩分类、软岩属性及软岩判定等方面的研究成果 ;并根据软岩巷道的围岩变形规律和压力特点 ,针对煤矿巷道使用及安全等方面的要求 ,论述了煤矿软岩巷道支护的基本原则 ,重点介绍了U型钢金属可缩性支架壁后充填、锚注加固等一些非常规性的 。
This paper systematically summarizes the results of researching the soft rock classification,attribution and judgement of China′s coal mine drifts;based on the deformation regularity and pressure features of surrounding rock of soft rock drifts and according to requirements in operation and safety of coal mine drifts also discusses the basic principles of supporting the soft rock drifts;and introduces some un normal but effective supporting means such as U steel yieldable set with wall back filling and bolt grouting.
