| 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。

| Abstract: | To satisfy the safety and stability requirments of mining roadway with large section in layered and soft ore deposits,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 I1 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 mining 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. |
