摘要
为了提高井下矿山矿石产能,减少资源损失,提高矿山充填能力,降低采矿成本,根据目前井下矿岩赋存复杂难采矿山的特点,针对地下矿山存在夹层矿多、矿房大块多、贫化大(或损失多)、生产和充填能力不足状况,对井下和露天转地下模式的矿山,提出了采用井下破碎—干选—充填联合工艺的建议。
In order to improve underground ore production capacity, reduce the loss of resources, improve the filling a- bility, and reduce mining costs, the joint process of crushing-dry separation-filling is proposed for the underground mine and the transferring from open-pit to underground mine according to the feature of the complex occurrence of underground miner- als, and such shortcomings as lots of banded-ore, much oversize ores, high ore depletion, and less production and filling ca- pacities.
