MGD250-NW型短壁采煤機(jī) MGD250-NW型短壁采煤機(jī)是一種特殊類型的單電機(jī)縱向布置,具有多種用途的單滾筒液壓無鏈牽引采煤機(jī),該機(jī)機(jī)身短,搖臂可在270°范圍回轉(zhuǎn),采用齒條油缸式調(diào)高。它特別適用于長度在20m~60m,傾角≤25°的綜采放頂煤工作面。當(dāng)工作面采用雙機(jī)工作時(shí),可作開缺口機(jī)用。它的問世,對(duì)急傾斜特厚煤層水平分層和“三下采煤”的綜合機(jī)械化開辟了廣闊的前景,為我國填補(bǔ)了這個(gè)領(lǐng)域的空白。 MG250-NW is a special multi-functional single-ended ranging drum Shearer . Itis particularly available for thefully mechanized short wall face with its length of 20-60 meters and inclination of ≤15°. It can be not only used as stablehole cutter but also the face opening and roadway headingmachine . The appearance of this machine open a vast vistas for sub-level caving extraction as well as fully mechanized winning under waters , railway or building andfills the gap in the field of coal mining machinery in our country.
