一、前言近几年来,振动放矿在国内之所以发展迅速,是因为它与重力自溜放矿相比,不论是技术上还是经济上都具有许多优点。该技术最早始于苏联。而今据不完全统计,苏联在覆岩下采用振动放矿的有底柱采矿法占80％,无底柱采矿法占5％;在非覆岩下放矿的空场采矿法(包括留矿法)占15％。其坑内矿山80％以上的出矿量是用振动放矿机完成的,因而在国际采矿界也引起了重视。如美国、瑞典等国近年都开展了这方面的研
I. Introduction In recent years, the reason why vibrating ore mines are developing rapidly in China is that they have many advantages, both technically and economically, compared with that of gravitational self-loosening. The technology was first started in the Soviet Union. According to incomplete statistics, there are 80% of bottomed-column mining methods using vibrating ore mined in the Soviet Union under the overburden and 5% of those without bottom-pillars mining method. The open-pit mining method (including retention method) 15%. More than 80% of the mine’s pits have been drained by vibration mills, which has drawn great attention from the international mining community. Such as the United States, Sweden and other countries have carried out research in this area in recent years
