本文以板石沟露天矿为例,剖析了矿山设计和生产状况,肯定了改原设计为分期开采以推迟前期生产剥采比是完全正确的,指出了扩帮过渡所面临的问题,论证了实行集中强化开采的技术可行性和经济效益,并将给我国露天矿的设计、生产提供丰富的经验和有益的启示。 In this paper, taking the opencast ore in Bandengou as an example, this paper analyzes the design and production status of the mine, confirms that it is completely correct to change the original design to staged mining so as to postpone the previous production stripping ratio, and points out the problems faced by the expansion and removal transition. We will implement the technical feasibility and economic benefits of intensive mining and will provide rich experience and useful enlightenment to the design and production of open-pit mines in our country.
