特厚坚硬高瓦斯大断面综放切眼锚网锚索耦合支护实践

The Bolt-cable Coupling Support Practice on Large Section Open-off Cut for Fullymechanized Sublevel Caving in Thick-hard Coal Seam of Gassy Mine

根据现场工程地质条件调查分析、岩石物理力学特性和特厚坚硬高瓦斯大断面综放切眼围岩力学变形机制及其转化研究,提出了特厚坚硬高瓦斯综放工作面巷道锚网锚索耦合支护设计方案。根据试验结果,证明在白芨沟矿采用锚网锚索耦合支护技术在技术上是可行的、安全上是可靠的、经济上是合理的。

Based on the analysis of geology condition, rock mechanics character, and deformation mechanics of surrounding rock of open-off cut in thick-hard coal seam and its transforming technology, the bolt-cable coupling support design was put forward. Based on the practice result, it is feasible on technology, credible on safety, and reasonable on economic by using the bolt-cable coupling support technology.
