Title: Automatic double action mining machine - with rotating cutters advancing in parallel cut from two sides of centre of seam and returning idle to commence next cut
Inventor: LANFERMANN WILLY ING GRAD
IPC: E21C41/20
Filed: 1978-06-12
Abstract: Mineral seams are reused by mining technique. This uses a rotating cutter, the position of which is controlled by a carrier arm. The seam is cut by two cutting machines working from either end of the shaft. These steadily remove mineral along the shaft, which is then conveyed to one end. The track is so arranged that one of the machines overlaps the cut of the other to ensure complete removal of the mineral. Both return to either end with the cutters in a resting position. The cutters are then readjusted for the next cut. Used esp. for mining soda and potash. If conventional cutters are used, progress is slowed near the centre of each cut to remove the last bit by manual operation. The new system automates this and increases productivity.
