在生产中,提升钢丝绳使用的好坏,直接响影到矿山提升的安全和经济效果。大宝山矿斜坡箕斗提升装置,于1976年3月投产,钢丝绳只完成提升量11.6万吨就被损坏,使用期限大约只有一个月,两根钢丝绳价值为31650元,如不考虑维护和换绳所花去的费用,折合提升一吨矿石为0.27元。本文对该矿斜坡箕斗提升钢丝绳损坏的原因作一初步分析,为设计和生产提供参考。
In production, to improve the quality of the use of wire rope, a direct shadow to mine to enhance the safety and economic effects. Da Baoshan mine slope skip lifting device, put into operation in March 1976, the wire rope to complete the lifting of 116,000 tons were damaged, the service life of only about one month, the value of two wire rope is 31650 yuan, if not consider the maintenance and change rope The cost spent, equivalent to an upgrade of 0.27 yuan ore. This paper makes a preliminary analysis of the reasons for the damage to the rope in skip slope of the mine and provides reference for the design and production.
