摘要
分析了大倾角工作面回采巷道所采用的工字钢梯形棚支护的诸多弊端,提出采用"锚网索"联合支护来代替梯形棚支护。支护实践表明,1701大倾角综采工作面回采巷道"锚网索"支护能够促使围岩支护由被动支护转为主动支护,改善了巷道围岩状态,提高了围岩整体性、完整性和承载能力,提高了安全生产水平。
Based on the analysis of disadvantages of I-steel support in the roadways of large inclined angle face, the author proposed bolt-net-anchor combined support to take place of I-steel support.Supporting practice showed that bolt-net-anchor combined support at 1701large inclined angle face could make passive support turn into active support,which improved roadway state,increased integrity and bearing capacity of surrounding and improved safety production level.
