    摘要:

    泗顶铅锌矿的古丹矿区采用平窿开拓,其最低开拓中段以下尚赋存在规模不大的矿体。对下部小矿体采用脉内斜井电耙出矿的浅孔房柱法开采。这种开采方法不需要的下部水平掘进运输巷道,减少了运输提升环节,因而可提高开采效益。本文详细介绍了该采矿法的汞切工程布置和回采工艺,及其主要技术经济指标。

    Abstract:

    In the Gudan mining district of Siding Lead-Zinc Mine, development has been carried out through driftway. There is an orebody of small scale lying below the lowest development level. The shallow hole room-and-pillar mining method was used to recover the small orebody in which an in-seam incline was driven for ore removal using electric scrapers. Using this mining system, it is unnecessary to drive horizontal transportation drifts at the lower level for haulage, thus eradicating the hoisting procedure and raising mining profitability. This paper deals in detail with the layout of mining drifts and development drifts as well as with the stoping procedure, along with its main technical and economical indices.
