目前为了加速主要采掘工程的进度,开始采用一种新的工艺过程。在新克里沃洛格采选公司的露天矿(图1)掘进+20米水平堑沟时,利用了一台上向装车的电铲和两台尽头装车的电铲。在等空车时,靠尽头工作面的一台电铲给在其后面的第二台电铲准备料堆。当空车来到尽头工作面时,两台电铲同时进行装车。这种装车方法再加上高质量的多排延发爆破,能保证岩石破碎质量很好并显著地提高了堑沟掘 At present, in order to accelerate the progress of the major mining works, a new process has been started. A trench shovel and two end-of-life shovels were used at the open pit mine (Figure 1) of the New Kerry Vorgo Mining Company for driving trenches up to +20 meters. When waiting for an empty car, rely on a power shovel at the end of the working face to prepare a stockpile for the second power shovel behind it. When the empty car came to the end of the face, the two shovels at the same time loading. This method of loading, coupled with high-quality multiple-row detonation blasting, ensures that the rock is broken and of good quality and significantly improves the cut and dig
