中文摘要：
为满足层状松软厚矿床大断面回采巷道的安全和稳定性要求,基于极限平衡理论和弹塑性理论,对新疆某矿I1采区7#层状特种厚矿床大断面回采巷道锚杆锚索联合支护问题进行研究。根据目前现场锚索施工的最佳长度,设计确定了回采巷道在矿床中的合理位置,配合现场常用的支护材料,优化了锚杆锚索联合支护的支护参数,为矿山的设计施工和生产管理提供了参考依据。
英文摘要：
To satisfy the safety and stability requirments of mining roadway with large section in layered and soft ore de- posits, the problem of combined support by bolt and anchor cable in mining roadway with large section of layered, special and thick ore deposit No. 7, mining area Il of a certain mine in Xinjiang Province was studied, based on the limit equilibrium theory and the elastic-plastic theory. According to the optimum length of anchor cable in construction, the appropriate location of min- ing roadway in ore deposits was determined ; the support parameters of combined support were optimized under the coordination of common supporting materials in construction, which offers a reference to the design, construction and management of mine.
