摘要
针对余吾煤业高应力高瓦斯矿井下的回采巷道,提出在煤帮侧采用高强玻璃钢锚杆支护系统。介绍玻璃钢锚杆的结构及优点,设计支护方案;并在N2202回风顺槽进行工业性试验。试验表明:采用玻璃钢锚杆支护,有效地控制了巷道围岩变形,实现围岩稳定性。
For high geostress and high gas Yuwu Mine, high strength fiberglass reinforced plastic bolt (FRP bolt) was proposed to use on the both sides of the driving roadway. The paper presented its structure and strengths of the FRP bolt and the supporting scheme. Industrial test was conducted on No.2202 return airway. The results showed that the FRP bolt effectively controlled the surrounding rocks deformation and realized the stability.
