Borehole Mining. No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jetcutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

Lignite is Abundant and Accessible. Lignite is more accessible than other types of coal because lignite veins are located relatively near the surface, eliminating the need for underground excavation in tunnels. Surface mining also eliminates the risk of methane or carbon monoxide buildup, a primary safety concern in underground mining.
