最近几年,苏联铁矿工业主要是开采埋藏较深的大型矿床,随着开采深度的增加必须强化剥离工作。更广泛地采用钢索斗铲可能是解决这一问题的一个方向。在苏联,尤其是在煤矿工业,积累了合理利用这类设备的丰富经验,应该加以总结并推广到黑色冶金矿山企业,以强化剥离工作。一些露天铁矿,在复杂的水文地质条件下已使用索斗铲开采沉积岩,直接向铁运车 In recent years, the Soviet Union’s iron ore industry has mainly exploited large deposits buried deep, and stripping work must be intensified as mining depth increases. The wider use of cable bucket shovels may be one way to solve this problem. In the Soviet Union, especially in the coal mining industry, accumulated rich experience in the rational utilization of such equipment should be summarized and promoted to black metal mining enterprises in order to strengthen the separation work. Some open-pit iron mines, which have used dragline shovels to extract sedimentary rocks under complex hydrogeological conditions,
