运用理论分析、数值模拟的方法,研究了首山矿11061回风巷道优化支护方案支护效果。现场应用表明:优化方案的锚杆参数显著改善了支护效果,巷道顶底板移近量64mm,两帮移近量66mm,为深部巷道锚杆支护参数优化提供了技术参考。
The theoretical analysis and numerical simulation are used to study the support effect of 11061 return airway optimization support scheme in Shoushan Mine. The field application shows that the anchor parameters of the optimized scheme have significantly improved the support effect. The top and bottom of the roadway moved nearly 64mm and the two approaches moved nearly 66mm, which provided a technical reference for the optimization of bolting parameters in deep roadways.
