本文论述胶结充填人工矿柱(壁)在一定条件下的承载作用。其条件是:水平或缓倾斜矿体及急倾斜厚矿体中的水平分层胶结充填采场,等间距排列的胶结充填人工矿柱(壁),中等坚硬的围岩和比较稳固的直接顶板或以杆柱加固的人工护顶。文中讨论了在所述条件下胶结壁接顶承载时的受力特征,研究了当顶板岩体(或矿体)具有弹性和塑性以及蠕变时胶结壁的支承载荷,分析了“采场顶板—胶结壁”整体的稳定性,探讨了开采深度、矿房跨度、胶结壁高度与宽度及胶结充填体强度之间的参数关系。
This article discusses the bearing effect of cemented pillar (wall) under certain conditions. The conditions are as follows: Horizontal tiered cementing and filling stopes in horizontal or gently inclined ore bodies and steeply inclined thick ore bodies, cemented and filled artificial pillars (walls) arranged at equal intervals, moderately hard surrounding rock and relatively stable direct roofing Or with pole reinforcement artificial escalator. In this paper, the stress characteristics of cemented wall under the above conditions are discussed. When the roof rock mass (or ore body) has elasticity and plasticity and the bearing load of cemented wall when creep is studied, - Cemented Wall "as a whole, and discussed the relationship between mining depth, mine spans, cemented wall height and width and cemented filling body strength.
