摘　　要：为保证瓮福磷矿穿岩洞矿南帮与东南帮露天采场终了边坡的稳定性,利用极限平衡法并考虑矿山经济效益来进行终了边坡的精细化设计,形成了分段式优化设计方案。然后利用数值模拟方法对最终方案进行稳定性分析。最终,充分利用上缓下陡两段式与上缓下陡中间过渡三段式优化方法,在安全系数均满足要求的前提下,对矿区东南帮和南帮边坡做出了优化,通过减少剥岩量为矿山创造巨大效益。In order to ensure the stability of the final slope of the open pit in the south and southeast sides of Wengfu Phosphate Mine,the limit equilibrium method and the economic benefit of the mine are used to carry out the fine design of the final slope,and the segmented optimization design scheme is formed.Then,the stability of the final scheme is analyzed by numerical simulation method.Finally,by making full use of the two-stage optimization method of upper-slow and lower-steep and the three-stage optimization method of upper-slow and lower-steep intermediate transition,under the premise that the safety factors meet the requirements,the southeast and south slopes of the mining area are optimized,and great benefits are created for the mine by reducing the amount of rock stripping.
