摘要
介绍了高强度锚杆支护技术,分析了易破碎顶板支护原理,该技术在A矿的两年实践表明:高强度锚杆组合配套支护在A矿使用以来,加快了掘进速度、降低了掘进成本、提升了安全保障,效果非常显著,值得推广应用。
The paper introduces high strength bolt support and analyzes its support principle for broken roofs. The two-year application in Mine A demonstrated： the support could speed up the driving, reduce cost, and improve safety, which was effective and worth spreading.
