长期以来,对溜口堵塞问题的处理,传统的办法是采用药包爆破处理,利用炸药引爆后的冲击能将堵塞拱破坏,达到矿石流畅通。这种处理方法,劳动强度大,人身安全得不到保证,费工、费时,材料消耗高,施工组织困难。同时,由于药包爆破后,冲击波是按球面波形向外传递的,因此对底板压实的粉矿基本没有什么破坏作用,致使堵塞频繁发生。 1983年2月,我矿平硐车间,根据射流原理,利用高压射流对固体物料的冲击力,成功地清除了溜井口底板上被淤积压实的粉矿,破坏了形成自然
For a long time, the traditional approach to deal with the problem of clogging the mouth is to use the explosive treatment of the bag. Using the impact after the detonation of the explosive can destroy the clogged arch and achieve smooth ore flow. This treatment method, labor-intensive, personal safety can not be guaranteed, labor-intensive, time-consuming, high material consumption, construction and organizational difficulties. At the same time, because of the explosion of the medicine bag, the shock wave is transmitted outwardly according to the spherical wave form, so there is basically no destructive effect on the compacted powder base on the floor, resulting in frequent blockage. In 1983 February, mine mine workshop, according to the jet principle, the use of high-pressure jet impact on the solid material, successfully cleared the slippery well floor silt compaction powder, destroyed the formation of natural
