【摘要】 介绍了在深凹岩石边坡少剥离技术时空原理研究方面所取得的进展,以及金堆城钼业公司的地质条件和开采条件。本文运用弹性力学原理推导出的边坡岩体在自重应力和构造应力作用下,椭圆形边坡处于临界下滑状态时的深度与边坡水平曲率半径之间的微分方程表达式,它的求解将把人们对深凹边坡稳定性的认识带到新的高度。更多还原

【Abstract】 The development of less-stripping technology of deep open pit slope, and the conditions of geology and mining in Jinduicheng molybdenum open pit have been introduced. Based on the theory of elasticity, the circumference stresses at the edge of the oval-shaped open pit caused by the deadweight of the rock and the horizontal virgin stress are derived. Then considering the critical sliding conditions of the infinitesimal element, the first order differential equation, which defines the relations between the depth and the radius of curvature of the slope was obtained, this will help people recognize the stability of deep slopes better.更多还原
