Method for extraction and transportation of coal in thin beds, in which the bed destruction and coal transportation are performed by means of knife chain with cutting heads at the ends of the knives at the side of the bed. At that cutting, loading and transportation of coal along the coal-face are performed during the motion of the upper branch of the chain along the lower one, while the last one moves over the bed base, with simultaneous displacement of those to the coal-face, due to the chains tension, the coal-face curvature and displacement of the transmission stars along the coal-faces.
