我国五、六十年代建设的露天矿,目前多数已进入深凹露天开采时期,从生产实践看,深凹露天矿后期开采阶段的工艺及技术管理等诸多方面,与中前期开采阶段有许多不同,需要矿山工作者认真认识和探讨,本文仅就白银露天矿开采实践,对深凹露天矿后期开采的一些特征进行了探讨。 At present, most of the open-pit mines constructed in the 1950s and 1960s have entered a deep open pit mining period. From the perspective of production practice, many aspects such as technology and technical management in the late mining stage of the deep-pit open-pit mine are different from those in the middle-early stage of mining. , Mine workers need to seriously understand and explore, this paper only on the practice of open-pit mining in silver, deep open-pit open-pit mining some of the characteristics are discussed.
