提高凿井提升机绳速,是提高凿井提升能力的有效措施之一。目前选用的提升机,最大绳速为5～6 m/s。根据《煤矿安全规程》的规定,允许最大绳速随井深增加而提高,既Vmax=0.4H~(1/2),这样可提高绳速近一倍。此规定是针对一般提升条件而言的,若改进滑架等设施,绳速可提高到16～20m/s。绳速提高后,除利用稳绳、滑架等控制吊桶摆动外,还应防止在吊桶高速下降 Improving the rope speed of sinking hoist is one of the effective measures to improve sinking capacity. Currently used hoist, the maximum rope speed of 5 ~ 6 m / s. According to “Coal Mine Safety Regulations”, the maximum allowable rope speed increases with the depth of the well, both Vmax = 0.4H ~ (1/2), which can increase rope speed nearly doubled. This requirement is for general lifting conditions, if the improvement of the carriage and other facilities, rope speed can be increased to 16 ~ 20m / s. After raising the rope speed, in addition to the use of stable rope, carriage and other swing swing control, but also to prevent the bucket from falling at high speed
