苏联东方金属矿科学研究所为实现壁后充填作业的机械化,制出了一种以喷射装置为基础,利用材料再松散、并直接从运输车辆中吸出的小型充填装置(图1)。
In order to mechanize the backfill operation, the Soviet Union’s Oriental Institute of Metal Sciences developed a small filling device based on an injection device that uses loose material and aspirates it directly from the transport vehicle (Fig. 1).
