摘要
某改扩建钨矿山原开拓方式为平硐+主、副竖井+盲斜井联合开拓,现根据矿体赋存状态,开采技术条件需进一步对开拓系统进行深部延伸。通过从可比基建工程量、可比基建投资、费用现值、可比工期几方面,提出的延深主井+新增副井、新增主副井、新增混合井三种开拓方案进行经济技术比较,最终认为混合井方案基建投资量少、投资少、经营费用低,对现在生产系统影响小,更为合理。
Mine developing is a major program of lasting importance for underground mine construction.In order to select a reasonable system,it is necessary to make a technical and economic comparison of the plan.A reasonable development program should be simple,easy to manage,safe and reliable,and has good economic benefits.At the same time,the amount of capital construction is small,the investment is low,and the time of capital construction is short.It can fulfil the need of production to the greatest extent.Existing project should be take account of especially for reconstruction and extension mine.In this paper,by comparing the amount of capital construction,capital construction investment,present value of cost and construction period,a reasonable development program is selected for a reconstruction and extension mine.
