Late Friday, Billings Federal District Court Judge Susan Watters ruled that a massive expansion of the Rosebud coal strip-mine was approved illegally. The expansion was approved in June 2019 by the federal Office of Surface Mining (OSM) and allowed Western Rosebud Mining, LLC (WRM) to strip-mine a new area, known as Area F.
Strip mining, where mountainsides are simply blasted away to expose the coal, was also employed. By the 1800s, over one million tons of coal were being culled annually, transported via an extensive canal network for distribution along the East Coast. By the mid-1900s, however, the mining industry began to decline.

Strip mining is a type of surface mining where the overlying vegetation, rock, and soil (overburden) is removed in order to reach the underlying coal seam, which usually lies a few feet beneath the surface. Explosives are used to fracture any overlying rock, and then heavy machinery is used to remove the overburden and dump it into a nearby area.
Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. …
