一、概况 随着采掘综合机械化的迅速发展和重型机械的大量使用,解决井下辅助运输问题,日趋迫切。根据有关资料,日产千吨煤炭平均所需的辅助运输量每班约为30人,即占井下总运输量的30—40％。为此,在一些主要产煤国家,自五十年代末起,单轨吊车就成为井下运输人员、设备 I. Overview With the rapid development of comprehensive mining mechanization and heavy use of heavy machinery, to solve the problem of auxiliary transportation underground, increasingly urgent. According to the relevant data, the average amount of auxiliary transportation needed per day for a tonne of coal is about 30 people per shift, accounting for 30-40% of the total underground traffic volume. To this end, in some major coal-producing countries, monorail cranes have become underground transport personnel since the late 1950s, with equipment
