永平铜矿是国家调整时期的重点建设项目,露天开采。选择合理的采剥方案,对于加速矿山建设和有效开采是十分重要的。本文对该矿的采剥方案进行了探讨,尤其着重讨论了基建和生产前期的采剥方案问题。(一)矿山概况永平铜矿属广义矽卡岩型矿床。以铜、硫为主,共生铅、锌,上部为铁帽。计有七个矿带,其中Ⅱ矿带是露天开采的主矿带。Ⅱ矿带铜硫矿体在6~1号勘探线之间比较肥厚,矿体形态似层状,其走向与岩层走向基本一致,近于南北,倾向东,倾角较缓,一般为20~30°。矿区岩石以混合岩和藕塘底群为主,次为第四系堆积物。混合岩主要为黑云斜长片岩、黑云斜长片麻岩、斜长角闪岩;藕塘底群由石英砂岩、千枚状页岩及矽卡岩化灰岩
Yongping Copper Mine is a key construction project during the period of national adjustment and is open pit mining. Choosing a reasonable mining scheme is very important for accelerating mine construction and effective mining. This paper explores the mining and stripping scheme of the mine, with particular emphasis on the issue of mining and stripping scheme in the capital construction and pre-production period. (A) mine profile Yongping copper mine is a generalized skarn type deposit. Copper, sulfur-based, symbiotic lead, zinc, the upper part of the iron cap. There are seven ore belt, of which Ⅱ ore belt is the main open-pit mining belt. Ⅱ ore belt copper-sulfur ore body 6 ~ 1 between the more prosperous exploration line, the ore body shape stratification, and its strike is basically the same with the rock strata, nearly north-south, east, dip angle is relatively slow, usually 20 to 30 °. The rock in the mining area is dominated by mixed rocks and lotus bottom, with Quaternary deposits secondarily. The mixed rocks are mainly biotite plagioclase, biotite plagiogneiss and plagioclase amphibolite; the lotus bottom group is composed of quartz sandstone, thousand-shaped shale and skarn limestone
