Mining in Manitoba
Shaft Pockets
Mining Systems
The shaft/loading pocket prepares the ore for loading on a skip. Oversize chunks are broken before entering the skip. Some mines use crushers to reduce the ore to about 6 inches in size. A measuring pocket is usually installed at the lower end of the storage pass. This holds only one skip full. There are protective devices to prevent this pocket from over-filling and spilling ore down the shaft. When the skip gets into position, the measuring pocket dumps rapidly into the skip.
