我矿东竖井用KJ2×2.5×1.2型提升机作业。井深100m,分-35m、+15m和+65m三个作业水平。300m长的钢丝绳有250m缠绕在卷筒衬木上,约32圈。由于在运行中一号卷筒绳头的30～50m段有严重断丝现象,截去50m以后仍旧使用。在调水平对罐时,罐笼仍能到达准确位置;但一旦升降时,罐笼在各水平就会错位。当二号罐笼下降到-35或+15m水平时,一号罐笼上升至+65m水平以后竟高出160mm左右,使矿车从罐内推出时冲击剧 I mine east shaft with KJ2 × 2.5 × 1.2 hoist operation. Well depth 100m, points -35m, +15 m and +65 m three job levels. The 300m long wire rope has a length of about 250m wound on a roll of wood, about 32 laps. As in the operation of the first reel 30 ~ 50m section of a serious broken wire, cut off after 50m still use. When adjusting the level to the tank, the cage can still reach the exact position; however, the cage will be dislocated at all levels once it is raised and lowered. When No. 2 cage dropped to -35 or + 15m level, No. 1 cage up to + 65m after the level was actually higher than about 160mm, so when the launch of the car from the tank when the impact of drama
