摘要
提出了一种新的煤矿井下综采面顶板控制方案,以顶板预应力结构理论为基础,以锚杆强化控制为核心,实现了科学、合理、高效的顶板支护控制方案,极大地提升了顶板支护效率和稳定性,对提升煤矿井下作业安全和经济性具有十分重要的意义。
Based on the theory of roof prestressed structure and the reinforced control of anchor bolt, a new roof control scheme for the fully mechanized face in coal mine is put forward, which realizes a scientific, reasonable and efficient roof support control scheme, greatly improves the efficiency and stability of roof support, and is of great significance to the safety and economy of coal mine underground operation.
