用露天法开采金属矿床时,露天矿年下降速度可达15～20米,其开采深度目前已超过200米。在这些条件下,矿石与剥离废石的连续采掘和运输方法,已成为采选公司采矿和矿石加工中为提高生产工作效率和保证完成生产任务的重要因素之一。由于广泛应用间断一连续运输工艺,预计地下的基建工程量将继续增加。 Open-pit mining method using metal deposits, the annual decline in surface mine up to 15 to 20 meters, the mining depth has now exceeded 200 meters. Under these conditions, the continuous mining and transportation of ore and pealed waste rock has become one of the important factors in the mining company’s mining and ore processing to increase production efficiency and ensure completion of production. Due to the widespread use of intermittent and continuous transport processes, the volume of underground infrastructural projects is expected to continue to increase.
