     · In this method, ore is mined in horizontal slices, starting from the bottom to the top of the stope. The broken ore is left in the mined-out stope and serves as a support to the stope walls and a working platform for mining the ore above. Shrinkage stoping has a high recovery but requires steep and narrow ore bodies.
