现在露天采矿发展的特点是建设生产能力大的深露天矿。近年来,人们对推行间断一连续工艺很重视;在间断-连续工艺中,主要物料是由胶带运输机,即用胶带运输机运输露天采场破碎机破碎后的矿岩。露天矿机械破碎硬岩有三种方式:一、 Open-pit mining is now characterized by the construction of large capacity of the deep open-pit mine. In recent years, people pay great attention to the implementation of the intermittent-continuous process.
