ABSTRACT:
A method of winning material in a mineral mining working utilizes a mineral mining plough which is movable to and fro alongside a conveyor. The plough is provided with first cutter means arranged to win material lying in a first height range, and second cutter means arranged to win material lying in a second height range. The plough is driven on the downhill run with the cutter means so positioned that material is won to a greater depth over the first height range than over the second height range. The plough is then driven on the uphill run with the cutter means so positioned that material is won to a smaller depth over the first height range than over the second height range.
