文档介绍：摘要
本设计为关门山露天矿开采设计方案,设计的年生产能力为140万吨,从2010年开始基建,2013年达产,开采年限97年。
设计包括露天矿合理帮坡角确定,采用境界剥采比不大于经济剥采比的原则圈定露天开采境界,选用公路汽车运输开拓。进行了掘沟工程量的计算,对生产能力进行验证并编制了采掘进度计划。对开采参数与程序、掘沟生产能力、均衡剥采比、爆破工程、采装工艺、排土,矿山工程进度计划等做了叙述。

Abstract
Guanmenshan is designed to close the open pit mining design, designed annual production capacity of million tons, from the beginning of infrastructure in 2010, production in 2013, 97 years mining life.
Design, including open-pit slope angle to help determine a reasonable use of state stripping ratio of not more than economic stripping ratio open-pit mining of the principle of delineation of state, chosen to open up the road motor transport. Trench digging work carried out the calculation of production capacity and to verify the progress of the preparation of a mining plan. Parameters and procedures for the mining, ditch digging capacity, balanced stripping ratio, blasting, mining equipment technology, exclusive territories, implementation schedule for the projects such as mine has done a narrative.
