Methods and equipment have been developed that combine the use of continuous miners, flexible conveyor trains, and longwall mining techniques to provide flexible and efficient removal of resources from subterranean formations. Some mining operations use a powered roof support comprising: a canopy configured to directly contacts a roof of a mine; a base configured to rest on a floor of the mine, the base comprising a spill plate and a push cylinder with a maximum stroke greater than 11 feet; and a pair of hydraulic legs attaching the canopy to the base.
