在露天转地下开采过程中,如何合理确定过渡时期及地下开采时期矿山的生产规模,做到不停产,维持矿山持续的生产能力,顺利的由露天开采转到地下开采是最重要的环节之一。矿山的生产规模是矿区开发过程中非常重要的一项决策要素,与此相关的决策要素还有矿山的服务年限等。在市场经济条件下,这些决策因素确定的正确与否,将对矿山开采经济效益与矿区可持续发展能力带来深远 How to reasonably determine the production scale of mines during the transitional period and underground mining period during the process of converting from open-pit to underground, so as to ensure the continuous production capacity of the mines without interruption of production and smooth transition from open-pit mining to underground mining is one of the most important aspects . The production scale of mines is a very important decision element in the process of mining development. The related decision-making elements include the service life of mines and the like. Under the conditions of market economy, the correctness of these decision-making factors will bring far-reaching impact on the economic benefits of mining and the sustainable development of mining areas
