摘要
基于3DEC离散元模拟软件对49709皮带巷的未支护、单棚梁支护和双棚梁支护三种方案进行了数值模拟计算,并结合实地勘探情况确定了49707皮带巷的最佳支护方式,制定相应的安全技术措施,以保证施工顺利进行。
Based on 3 DEC discrete element simulation software, the three schemes of unsupported, single shed beam support and double shed beam support in 49709 belt roadway are numerically simulated and calculated, and the best support mode of 49707 belt roadway is determined according to the field exploration situation, and the corresponding safety technical measures are formulated to ensure the smooth construction.
