摘要
以五阳煤矿南丰76采区生产系统受天仓向斜、断层带和陷落柱群等地质构造影响巷道破坏变形严重为背景,介绍了动压巷道围岩变形破坏机理。通过采用注浆与锚杆锚索强力支护综合加固技术,使围岩体结构得到改善,破碎围岩恢复了完整性,承载能力得到有效提高,可锚性增强,能够为锚索提供足够的锚固力。围岩在高应力作用下发生变形的趋势受到锚索制约,并显著提高了围岩抗扰动能力,实现了矿井的安全生产。
Wuyang Coal Mining area,Nan Fung production system by 76 days of storage syncline,fault and collapse columns of geological structures such as roadway base damage deformed as the background,the dynamic pressure surrounding rock deformation mechanism.Anchor grouting through the use of strong support and comprehensive strengthening technology,the rock mass structure has been improved,restored the integrity of broken rock,effectively improve the carrying capacity can be enhanced anchor,able to provide adequate cable anchoring force.Rock under high stress in the trend of deformation constrained by the anchor,and significantly improve the anti-disturbance ability of the rock to achieve the mine＇s safety.
