摘要
根据现场工程地质条件调查分析、岩石物理力学特性和超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 ,提出了超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 。
Base on the analysis of the geological conditions, rock physical mechanics features and mechanics deformation mechanism of the surrounding rock of large cross section open off cut of fully mechanized caving face in ultra thick hard high gassy seam, the paper provided a design plan of a combined support with bolt mesh anchor for the gateway of the caving face. According to the result, the test showed that the combined support technology with the bolt mesh anchor used in Baijigou Mine is feasible in technology, reliable in safety and rational in economy.
