作为采矿主要生产环节之一的出矿作业,过去一直沿用重力放矿工艺,卡块和结拱现象经常发生,出矿作业效率低、安全性差、劳动强度大,成为井下生产的薄弱环节,严重影响井下工人劳动生产率和矿井产量。为了强化出矿过程,完善采矿工艺,改变出矿作业的落后面貌,我国于1974年开始了振动出矿技术的研究。几年来,特别是1978年以来,振动出矿设备的研制及其在工业中的应用都取得了显著的成效。 As one of the major production processes of mining operations, gravel mining has been used in the past. Blocking and arching frequently occur. The efficiency of mine operations is low, the safety is poor, and the labor intensity is high, making it a weak link in underground production. Affect downhole workers productivity and mine production. In order to strengthen the process of mining, improve the mining process, change the backwardness of the mining operations, China began in 1974, the vibration of the mine out of technology research. Over the past few years, especially since 1978, the development of vibration mining equipment and its application in industry have achieved remarkable results.
