露天转地下开采过渡模式综合评价

Comprehensive Evaluation of the Mode of Transition from Open-Pit to Underground Mining

针对唐钢石人沟露天转地下开采过渡模式评价问题,提出了1种综合评价方法,研究了露天和地下开采在时间、空间、综合产能及开采工艺系统上的衔接程度,实现了量化评价。结果表明,石人沟铁矿露天和地下开采时间结合程度低,空间上联系较紧密,矿床综合产能可能利用程度很小,露天和地下开采工艺系统的联系较为薄弱,缺乏统一、全面的规划。

A comprehensive evaluation method was proposed for the mode of transition from open-pit to underground mining of TangSteel Shirengonr Iron Mine, which considered the linkage degree betweem the open-pit mining and underground mining in time, space, integral production capacity and mining system, and realized a quantitative evaluation. The result indicates that the open-pit mining and underground mining of this mine have a low linkage degree in mining time, close relation in space, very low degree in utilizing its integral production capacity, and weak linkage betweem the two mining systems, and lack a unified all-sided plan.
