某矿１台ＪＫＭ３．５×６型多绳摩擦提升机，作为主井提升矿 石用，选用１４ｍ３底卸式箕斗，年提升矿石能力１８０万ｔ。经过近１０年的运行后箕斗斗箱磨损，箕斗框架变形，主要受力部件疲劳损伤，强度降低。由于斗及框架的变形，已将井塔楔形木罐道损伤，并且装卸矿时撒矿现
A mine a JKM3.5 × 6-type multi-rope friction hoist, as the main shaft to enhance the ore, the choice of 14m3 bottom dump skip, the annual increase of 1.8 million tons of ore capacity. After nearly 10 years of operation, the bucket hopper wears out, the frame of the skip deforms, the fatigue of the main force components is damaged and the strength is reduced. As a result of the deformation of the bucket and the frame, the well wedge-shaped wooden can road was damaged,
