MG250/300-NWD型短壁电牵引采煤机 MG250/300-NWD型短壁电牵引采煤机是一种特殊类型的,多电机驱动横向布置的单滚筒电 牵引采煤机,它特别适用与工作面长度在200m~600m之间,工作面倾角小于15°的短综采面,对 于长工作面,采用双机工作时,它可作为开缺口机用,具有广泛的适应性和灵活性,它的问世, 对急倾斜特厚煤层水平分层和“三下采煤”的综合机械化开辟了广阔的前景,为我国填补了这个 领域的空白。 MG250/300-NWD is a special multi-functionalsingle ended ranging drum shearer . It isparticularly available for thefully mechanizedshort wall face with its length of20-60meters andinclination of ≤10°. It can be not only used asstable hole cutter but also the face opening and roadway heading machine. The appearance of this machine opens a vista for sub-level cavingextraction as well as fully mechanized winn -ingunder waters, railway or buildings and fills the gapin the field of coal mining machinery in our cou -ntry.
