摘要
针对采用传统支护方案解决运输顺槽巷道顶板矸石不稳定的问题依然存在顶板冒顶和漏顶的事故风险,以运输顺槽巷道为研究对象,在分析其地质、水文、煤层等条件的基础上,分析了该运输顺槽巷道的施工现状和顶板矸石冒落的情况,为其设计浅孔注浆支护和深孔注浆支护方案。经实践证明,深孔支护方案较浅孔支护方案具有较佳的支护效果。
In view of the instability of roof gangue in transport tunnel, the roof caving and leaking accidents still exist in the traditional support scheme. Based on the analysis of geological, hydrological and coal seam, the paper analyzes the construction status and roof gangue caving in the transport tunnel, and designs shallow hole grouting support and deep hole grouting support scheme for it. It is proved by practice that the deep hole support scheme has better support effect than the shallow hole support scheme.
