常村煤矿主井提升系统采用单绳缠绕竖井提升,一直使用NAT光面圆股等捻角钢丝绳。近年来该矿通过扩建改造,箕斗装载质量由原来的5t增加到7t,钢丝绳直径由原来的34mm改为37mm,但仍无法满足生产的要求。钢丝绳的使用寿命约为2.5
Changcun Mine main shaft hoisting system using single rope winding shaft to enhance, has been using the NAT smooth round stock angle twist rope. In recent years the mine through the expansion transformation, skip loading quality increased from the original 5t to 7t, wire rope diameter from the original 34mm to 37mm, but still can not meet the production requirements. The service life of the rope is about 2.5
