摘要: 利用数值模拟技术,模拟并分析了锚网索与底角锚杆耦合支护机理,并以某矿为工程背景,模拟并分析了高水平应力条件下合理的锚网索+底角锚杆+桁架耦合支护结构,提出了在高应力条件下,巷道的破坏是扭曲变形破坏,采用合理的锚网索与底角锚杆支护结构和支护参数,可有效控制巷道扭曲变形,取得良好的支护效果。

Abstract: Using numerical simulation technology, coupling support mechanism of anchor-mesh-cable and bottom-anchor has been analyzed. According to actual engineering of a coal mine, the reasonable coupling support structure of anchor-mesh-cable and bottom-anchor under high stress has been analyzed. It is proposed roadway damage is twist deformation under high stress. Using the reasonable coupling support structure and parameter of anchor-mesh-cable and bottom-anchor can control and get good supporting effect.

Key words: Anchor-mesh-cable, Bottom-anchor, Numerical simulation, Coupling support
