摘要
文中针对石拉乌素煤矿22采区202工作面开采条件,分析了蒙陕地区大埋深大断面回采煤巷顶板锚杆锚索协同支护机理,形成了适应于蒙陕地区大埋深大断面煤巷的协同优化控制支护技术,提出了优化合理的支护方案并成功应用于现场。
Taking the track transportation roadway of 202 mining face in 22 mining area of Shilawusu coal mine as an engineering background,the collaborative supporting mechanism of bolt and anchor in roof for large section coal roadway in Shaanxi and Mongolia deep area were analyzed. Simultaneously,the Collaborative optimization control technology for surrounding rock of large section coal roadway in Shaanxi and Mongolia deep area was proposed,then a optimized and reasonable support scheme had been formed and successfully applied in practice.
