从白银公司的露天开采试谈经济合理的开发露天矿山本文为白银露天矿的生产经验总结。该矿于1956年基建,1959年投产,1965年达产,1971年超过设计生产能力,15年持续生产,1981～1982年即将结束。在生产过程中对原设计进行多次修改,形成了一个使用陡工作帮坡角分期扩帮开采,新水平开拓采用无开段沟或短开段沟、横向开拓的露天开采新工艺。
Discussion on the Economic Development of Opencast Mine from the Open Mining of Silver Company This paper summarizes the production experience of opencast mine of silver. The mine in infrastructure in 1956, put into operation in 1959, reached production in 1965, 1971 more than the design and production capacity, 15 years of sustained production, 1981 to 1982 is coming to an end. During the production process, the original design was modified many times to form a new open-pit mining technology that uses steep work to help slope angle expansion by stages and a new level to open up the trench with no opening or short opening.
