Abstract

842,614. Mineral-mining apparatus. COAL INDUSTRY (PATENTS) Ltd. July 30, 1957 [Aug. 2, 1956; Nov. 23, 1956], Nos. 23886/56 and 35936/56. Class 68(1). The apparatus is designed for the cutting of stable holes and consists of a short conveyer 13 on which is mounted a cutting machine having two cutter drums 6 so positioned on the machine for rotation about vertical axes that the cutter drums 6 make a cut at least equal in length to that of the conveyer as the machine is moved along the entire length of the conveyer. The conveyer may be of the paddle type or of the scraper type. The machine runs on a part of the conveyer frame within the path of the flights when the conveyer is of the paddle type or on the side frame of the scraper conveyer adjacent the face. Hydraulic piston cylinder units 7, 8, 9, 10 or a fixed chain engaging with a driven gear wheel of the machine are provided for moving the machine along the conveyer. Endless cutter chain carrying jibs may be associated with the cutter drums, whilst plough structures are provided for loading cut mineral to the conveyer. A pre-cutting cutter bar may be provided on the machine.
