我矿向阳坑井下出矿采用三个中段集中提升的出矿方式。因多中段同时作业,为调节各中段的出矿量,主溜井采用接力式溜井。过去对非集中中段溜井漏斗及闸门的设计比较复杂,不但开凿工作量和混凝土工作量大,而且造价也很高,检修也很困难。考虑到非集中中段漏斗闸门只起控制和转放矿石作用,与运输设备不发生任何联系,为此我们在 Mine mine to Yang pit underground mining using three central focus of the way to enhance the mine. Due to the simultaneous operation of more middle sections, in order to adjust the output of the middle section, the main-shaft adopts the relay-typed chute. In the past, the design of chute funnels and sluices in the non-centralized middle section was rather complex. Not only the workload of cutting and the workload of concrete was large, but the cost was also high, and the maintenance was also very difficult. Taking into account the non-concentrated middle of the funnel gate only play the role of control and transfer of ore, and transport equipment does not make any contact, for which we in
