控制矿石溜井冲击风流的技术措施

Technical measures for control of impact air flow in orepass

向溜井卸矿将产生冲击风流，风流中央带有粉尘会污染井下空气。文中阐述了设计溜井时须结合矿山条件对溜井的井位、结构型式、井口密闭等采取相应的技术措施。

The impact air flow could be formed when dumping the ore into the orepass and the dust contained in such flow resulted in the pollution of underground atmosphere. Sume technical measures for controlling the impact air flow to be considered in the design of orepass position,structure and collar seal according to the particular mine conditions were discussed in this paper.
