Featured Project
Turkey Gap Coal Refuse Mine Reclamation

Consol Energy of Cannonsburg, Pa., contracted DHGI in 2011 to provide the reclamation of the 25-acre Turkey Gap Coal Refuse Impoundment in Dott, West Virginia. The project had multiple factors that made it challenging. Project involved work in a remote area of West Virginia at extremely high elevations with very steep grades; pumping down a very deep three acre coal slurry pond and breach of its 50 foot dam in the dead of winter; and excavation and removal of a large quantity of coal slurry. The coal slurry removed was disposed of in onsite pits and capped with clean dirt. The remaining coal slurry was left in place and covered with 430,000 cubic yards of borrow dirt which was compacted to insure positive surface drainage. To stabilize the 25 acre site, new detention ponds were installed with permanent drainage structure and roughly 3,500 linear feet of grouted rip rap ditches. Following completion of the project, Consol was awarded the West Virginia Coal Associations top honor for mine reclamation work when they received the Greenland’s Award for their reclamation efforts at Turkey Gap.
