The Influence of Surface Coal Mining on Runoff …

Surface coal mining in mountainous regions typically involves the removal of overburden materials by blasting to expose coal seams and relocation of the overburden material (termed ''coal spoils'') into adjacent valleys. This process can result in headwater streams being buried beneath large volumes of overburden (i.e., waste rock), which alters the runoff dynamics.
