目前,为了强化放矿作业,广泛采用各种不同结构的振动放矿机,其中某些性能较好的(-4TM、-5、-4.5/1.4和型)已在克里沃罗格矿业公司的“五·一”矿山管理局通过了比较试验阶段。许多研究证明,在采用振动放矿机放矿工艺的条件下,放矿机的埋设深度是有限度的,超过此限度放矿口的有效截面就不再增大。这就最有效地限制了利用坑内运输和破碎机的可能性。因为在放矿口出现了1200毫
At present, in order to strengthen the ore extraction operation, a wide range of vibration mining machines with different structures are used. Some of the better ones (-4TM, -5, -4.5 / 1.4 and type) have been widely used in Kerry Vorogula Mining Company The “May 1” Mine Management Bureau passed the comparative pilot phase. Numerous studies have shown that there is a limit to the depth of burial mines under the conditions of using the vibrating ore miner for ore drawing, and the effective cross-section of the ore mines no longer increases if this is the case. This most effectively limits the possibility of utilizing pit transportation and crushers. Because in the mine mouth appeared 1200 milliliters
