铁山南矿业分公司东翼主提升系统存在运行环节多、操作人员较多、安全管理难度大、运行费用高、安全系数低等问题，不能满足矿井安全生产的需要。针对以上问题，通过对原来的主提升系统进行优化，选择主提升胶带输送机来完成该系统的工作任务，极大地提高了系统的安全系数，减少了操作人员，降低了运行费用，满足了东翼系统安全生产需要。%The east-wing main hoisting system in Tieshannan Mining Company can't meet the safety requirements due to its multiple operation links,more operators,difficult safety management,high operating cost and lower safety factor. To counter above problems,optimization was carried out to the original main hoisting system and the main hoisting belt conveyor was selected to do the main hoisting,which greatly increased safety factor of the system,reduced the operator,lowered the operating cost and met the requirements for safe production in the east wing.
