摘要
针对深部软岩巷道支护技术难题,以象山矿21501运输巷道为工程背景,通过理论分析、数值计算以及现场实测相结合的方法,对巷道的破坏特征进行研究,并提出相应的支护方案。结果表明:锚网索+锚杆联合支护方案可以有效控制巷道围岩变形。
Based on the deep soft rock tunnel excavation support problem of Xiangshan mine 21501 haulageway,combined with theoretical analysis, numerical calculation and supporting test on site to the study the deformation damage mechanisms and supporting technology. Results show that anchor（cable）combined supporting can make the effective control of surrounding rock of roadway.
