在暗井中掉换提升钢丝绳是一种经常须进行的工作。煤矿规程具体规定了钢丝绳的使用寿命,并根据钢丝绳的磨损情况而定。由於提升荷载的加重,提升钢丝绳的直径已经随而增大,以便增加需求的张力。在六十和七十年代的暗井中,钢丝绳的直径还只用到30毫米,而八十和九十年代其直径将为40毫米及以上。过去,掉换钢丝绳要安装两台临时绞车。但由于目前钢丝绳直径和重量的增大,从安 Changing a hoist rope in a dark hole is a work that often needs to be done. Coal mine regulations specify the life of the wire rope, rope wear and under the circumstances. As the lifting load aggravates, the diameter of the hoisting ropes has been increased in order to increase the required tension. In dark wells in the 60s and 70s, the wire rope used only 30 millimeters in diameter, while in the 80s and 90s it would have a diameter of 40 millimeters and above. In the past, two temporary winches were to be replaced by wire rope replacement. However, due to the current rope diameter and weight increase, from the safety
