Industrial Minerals
Mineral deposits (that are not consolidated rock) of sand and gravel are also used. Rock is also crushed into specific sizes to produce "crushed stone" for road base and fill material. Shale can be extracted fairly easily without crushing for similar purposes. Mining of noncoal/industrial minerals is a major industry.
