深井特厚复合顶板巷道支护原则探析

Analysis on Roadway Supporting Principles of Extra-thick Composite Roof in Deep Mine

针对深井高地应力影响下,特厚复合顶板巷道支护难点,本文在前人研究成果的基础上,首先分析了复合顶板的离层破坏形式及发展机理,深入分析了顶板破坏的影响因素,最后依据研究成果对巷道支护原则进行分析及总结,对相似地质生产条件下的巷道开拓及支护设计提供了借鉴。

In view of the difficulty of roadway support with extra-thick composite roof under the influence of deep mine highland stress,this paper first analyzes the damage form and development mechanism of the separated layer of the composite roof and the influencing factors of roof failure,and finally analyzes and summarizes the roadway support principles based on the research results,which provides a reference for roadway development and support design under similar geological production conditions.
