安庆铜矿主井承担着矿石、废石及部分检修材料的提升运输任务,年提升量达120万t,作为咽喉要道设备,主井提升机能否安全运行对矿山安全生产关系重大。1主井提升机存在问题该矿主井于1991年3月投产运行,提升机型号为JKMD-4×4。由于长期满负荷运行,提升机闸盘偏摆量超过规定标准值,先后于2002年和2004年更换闸盘,但是效果都不理想。期间采用车削、火焰校
The main shaft of Anqing Copper Mine undertakes the task of upgrading and transporting ore, waste rock and some maintenance materials with an annual increase of 1,200,000 tons. As a key equipment for the throat, whether the main shaft hoist can operate safely has a great bearing on mine safety production. A main shaft hoist problems The mine shaft was put into operation in March 1991, the hoist model JKMD-4 × 4. As a result of long-term full-load operation, improve the deviation of the brake disc more than the required standard value, has replaced the brake in 2002 and 2004, but the effect is not satisfactory. During the use of turning, flame school
