Abstract

1424202 Tunnelling ANDERSON MAVOR Ltd 25 Jan 1973 [12 Feb 1972] 6655/72 Heading E1F Mineral mined from a tunnel face by a mining machine located within a shield falls upon an apron 1A located at the lower leading end of the shield and is swept over the apron onto a conveyer 3 by oscillating paddles 23 disposed on opposite sides of the vertical medial plane of the shield, the paddles being connected by mechanisms as disclosed in referred to Specification 681037 to discs 21 lying in the plane of the upper surface of the apron and being connected to drive shafts of motors 19 housed in the apron. Controlled traversal of the cutter of the mining machine over a tunnel face is obtained by a cam follower on the cutter-carrying boom of the machine engaging with a cam track mounted on the leading end of the shield to extend transversely thereof and by jacks 6. 7 that control movement of the boom about an upright and a horizontal axis respectively.
