多中段同时开采矿山井下排水方案研究

Study on underground drainage scheme for multi-level mining

采用充填法开采的矿山为了实现更高产能的要求,采用多中段同时开采方式。对于多中段开采的井下矿山而言,排水系统采用直接排水系统还是接力排水系统,只能根据矿山特定条件通过技术经济比较进行选择。本文以某金属矿山为例,从技术经济方面对该矿山的排水方案进行综合评述,为相关的矿山排水系统设计提供参考。

Multi-level mining is used in mines with backfilling mining method in order to increase production capacity. For multi-level mining, the drainage system, which is divided into direct drainage system and relay drainage system, should be selected based on the mine site conditions and by technical and economic comparison. In this paper, a metal mine was selected as an example,the drainage scheme was reviewed comprehensively, and it provided a reference for the design of underground drainage system.
