我矿新风井担负着升降人员、提煤、提矸石和下料等任务。采用了国产JKM2.8×4多绳摩擦提升机,该机配有盘形制动系统和弹簧基础减速器,电机型号为JRZ100—12,功率为1000千瓦,采用交流金属电阻控制系统加动力制动。 JKM2.8×4提升机自1972年4月20日投产以来,运行情况基本良好,但由于提升机采用了一些新技术,新结构,又是首次在我矿使用,情况不太熟悉,操作比较生疏,对于如何掌握好操作规律,我们也是在实践中逐步摸索,经历了一个从不熟悉,不自由到比较熟悉、
I mine fresh air shaft responsible for lifting staff, mentioning coal, refuse collection and other tasks. Using a domestic JKM2.8 × 4 multi-rope friction hoist, the machine is equipped with a disc brake system and spring-based reducer, the motor model JRZ100-12, power of 1000 kW, the use of AC metal resistance control system plus power system move. JKM2.8 × 4 hoist since April 20, 1972 put into operation, the operation is basically good, but because of the hoist using a number of new technologies and new structures, but also for the first time in mine use, the situation is not familiar with the operation comparison Unfamiliar, how to master the operation rules, we also gradually explore in practice, has gone through a not familiar with, not free to be more familiar with,
