井下破碎-干选-充填联合工艺探讨

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。

Discussion on Application of Underground Crushing-Dry-Filling Process

In order to improve underground ore production capacity，reduce the loss of resources，improve the filling ability，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 minerals，and such shortcomings as lots of banded-ore，much oversize ores，high ore depletion，and less production and filling capacities.
