(1)依靠国内工业(卡尔宾斯克机械制造厂)实现露天矿炮孔填塞机械化,批量地生产了载重为5吨的-1型炮孔填塞车。这种填塞车在技术上落后,在结构上有很大缺点(从后侧往炮孔中填塞),即这种填料法超出操作司机的视线范围。加之需要调车作业,这些填塞车的实际生产能力显著的降低了。 (1) Relying on the domestic industry (Karpinsk Machinery Factory) to realize the mechanization of blasting of open pit mines, the -1 type of grate plugging truck with a capacity of 5 tons was produced in batches. This tamping truck is technically backward and structurally very disadvantageous (from the rear side to the bore hole), which means that the filling method is beyond the operator’s line of sight. Coupled with the need for shunting operations, the actual production capacity of these trucks has been significantly reduced.
