摘要
小型地下矿山在建设之初,多因地质储量、资金等各种实际问题,先以小规模开工建设,嗣生产一段时间之后,再扩建改造。本文就技术改造程序、资源回收、经济效益等问题进行了较详细的探讨。
The small-sized underground mines are usually constructed due to vague geological resources, shortage of capital fund or some other problems existed.Through a length of time in production and with the change of conditions, the expanding or remoulding of the small-sized underground mines are placed on the order of the day. This paper explores in detail on the technical remoulding procedure, recovering of resources, economic benefit and so on.
