摘要
基于某矿现场测量状况和工程基本情况,对巷道锚固体强度情况进行研究,提出针对综放工作面大断面沿顶巷道的支护设计优化方法。通过巷道支护参数设计、巷道围岩模拟、锚杆类型和支护结构.预紧力、锚杆直径、构建模型等方面进行优化,经试验验证了优化方案的有效性,从而确保综放工作面大断面沿顶巷道支护设计的可靠性,满足了矿井生产要求。
Based on the measurement condition of a mine site and the basic engineering situation,the strength of the anchor solids in the roadway,was studied,and the optimization method of the support design was proposed for the large section along the top of the roadway at the header face.This ensures the reliability of the design of the large cross-sectional support along the roof of the header face and meets the mine production requirements.
