一.概述近年来,在多绳提升矿井中,提升容器以很高的速度运行,运行中由于电气元件失灵或因司机操作失误,经常发生过卷事故。目前,国内多绳提升最高速度已达15米/秒,国外已超过20米/秒,提升容器如全速过卷,而不采取有效措施,势必造成严重后 I. Overview In recent years, in multi-rope hoisting mines, hoisting containers have been operating at high speed and frequent roll-over accidents during operation due to failure of electrical components or mistakes in driver operation. At present, the maximum speed of multi-rope hoisting in China has reached 15 m / s and that of foreign countries has exceeded 20 m / s. If containers are to be hoisted at full speed rather than effective measures, it is bound to cause serious problems
