Mineral Mining

Check all of the following mining methods which would most likely be used to mine salt.

• solution mining

In longwall mining,

• a network of entries is cut into seams of ore deposits

• ore is mined downward, layer by layer

• a shearer is moved back and forth across the face of the seam

• hot water is injected into the ore to dissolve the ore, and then air bubbles lift the ore to the surface
