湖南雄黄矿盲竖井提升,原采用一个天轮的单绳单卷筒提升系统,无断绳保险装置,因此安全性差。在该矿井筒改造施工中,为确保安全生产,对提升方式作了改进,变单绳提升为双绳同向提升,使其具备多绳摩擦提升安全可靠之特点。改进后的提升系统见示意图。 The blind shaft in the realm of Xionghuang Mine in Hunan Province was upgraded. The single rope single drum hoisting system using a natural wheel did not have a broken rope safety device, so the safety was poor. In the reconstruction of mine shaft, in order to ensure safe production, the way of improvement was improved, and the single rope was upgraded to double rope with the same direction to enhance the safety and reliability of multi-rope friction. Improved system to enhance the schematic.
