解决大深度提升有用矿物的最重要课题之一,是制造高强度提升钢丝绳。采用钢丝绳的横截面积从绳的上端到下端逐渐减少的等强度钢丝绳最为有效。在一些文献中[1—3]早就讨论过制造这种钢丝绳的想法,但实现这种想法遇到了很大的困难。实际感兴趣的是直径不变的轻填充等强度
One of the most important topics for solving the profound problem of enhancing useful minerals is to manufacture high-strength wire rope. An isosceles wire rope that uses a wire rope whose cross-sectional area gradually decreases from the upper end to the lower end of the rope is most effective. The idea of making such wire ropes has long been discussed in some papers [1-3], but great difficulties have been encountered in achieving this. What is actually of interest is the constant light-filled, constant-diameter strength
