强化露天矿的开采,为发展国民经济提供更多的原料,对加速四个现代化的建设,具有重要的意义。现就强化开采的有关采矿技术、工艺和措施,作如下浅谈: 一、新建的露天矿山尽可能减少基建剥离量,达到投资少、早投产、快还本。一般来说,基建剥离费用占露天矿总投资比例相当大,在建设时间上,基建剥离量的多
To strengthen the exploitation of surface mines and provide more raw materials for the development of the national economy is of great significance to speeding up the construction of the four modernizations. The following is a briefing on the relevant mining technologies, techniques and measures for enhanced mining: First, the newly constructed open pit mine should reduce the amount of stripping of infrastructure as much as possible to achieve low investment, early production and fast payback. In general, the cost of infrastructure stripping accounts for a considerable proportion of the total investment in open-pit mines. In terms of construction time, the amount of infrastructure stripping
