摘　　要：传统的露天矿开采境界为固定帮有台阶、露天底平面型。本文以四川会理岔河锡矿露天采场边坡为工程实例,介绍了露天矿无台阶边坡、非平面露天底开采境界的研究与设计过程和方法;论证了该种开采境界的适用条件及生产过程中应采取的安全措施;阐述了其技术经济效果。Traditional open-pit mining boundary features fixed slope with benches and planar bottom. Taking for example the open-pit mining slope of Chahe Tin Mine located in Huili County, Liangshan Prefecture,Sichuan Province, this paper presents the process and methods of research and design for open-pit mining boundary with fixed slope, no benches and non-planar bottom, and proves its applicable conditions and measures to be taken for safety purpose in production. It also gives an exposition of its technological and economical effectiveness.
