摘要
在矿山井下掘进施工中,综采开切眼的支护,历来是掘进支护工作的一个难题。文章讨论了高强度预应力锚杆及锚索护技术的先进性及安全可靠性。通过理论论证,支护效果比较,支护优点分析,充分证明高强度预应力锚杆+W钢带+锚索支护的先进性。
Comprehensive cut support has been being a puzzle for excavating in coal mine. This article discusses the advantage and safe reliability of high prestressing force anchor and wire mesh. According to the theofical proof, the comparison of result support shows the advantage of support.
