回采巷道不同锚固结构稳定性研究

Research on the Stability of Different Anchorage Structure in Gateway

运用理论分析和现场试验的方法,对普通锚固结构和整体拱形锚固结构的稳定性进行对比研究。结果表明,巷道采用普通锚固结构存在着结构松散,巷道易于失稳,而采用整体锚固结构大大提高了巷道围岩的整体稳定性的结论。

Through the theoretical analysis and industrial test , the stability of ordinary anchoring structure and integral arch anchoring structure are studied in details, the result indicates that the surrounding rock stability was improved with the integral arch anchoring structure.
