我国大型矿井近年来由于采掘综合机械化的发展，产录和效率有了很大的提高，但全员效率却上不去，其中一重要原因就是井下辅助运输机械化水平太低，大量人员用在运料、运设备上。如果说综采综掘的技术装备我们与世界先进采煤国家的差距已经不很大，那么在辅助运输方面的差距就 In recent years, due to the development of comprehensive mechanization of mining in China’s large-scale mines, the output and efficiency have been greatly improved, but the full efficiency has not gone up. One of the important reasons is that the mechanization of underground auxiliary transportation is too low. Material, transport equipment. If we say that the technical equipment of fully mechanized mining and mechanization of the advanced coal mining countries in the world, the gap between us is not great, then the auxiliary transport gap
