随着煤矿大型化,大量的不规则块煤和边角煤随之增加,但是现有的采煤设备无法实现边角煤和不规则煤块机械化开采,造成生产效率低,资源回收率低,工人劳动强度大。为了实现边角煤和煤柱等的机械化开采,论述一种采煤工作面长度小于30 m时的采煤装备,它是一种适合于超短壁安全、高效综合机械化的无链牵引双驱窄机身截煤机。 With the large-scale coal mines, a large number of irregular lump coal and corner coal will increase. However, the existing mining equipment can not realize the mechanized mining of corner coal and irregular coal lumps, resulting in low production efficiency and low resource recovery rate, Workers work hard. In order to realize mechanized mining of corner coal and pillars, a coal mining equipment whose coal mining face length is less than 30 m is discussed. It is a chainless traction double drive suitable for safe and efficient ultra-short wall mechanization Narrow machine cutters.
