Reactivation of Landslides by Surface Subsidence from Longwall Mining.
Am Assoc Petrol Giol Bull 1984 Dec; 68(12):1 pages
Subsidence research by the U.S. Bureau of Mines has identified and documented the occurrence of landslides over a longwall mining area in the Dunkard Basin. Most of these landslides occurred in masses of slumped hummocky soil generally associated with limestone and claystone beds of the Washington and Greene Formations. Identification and characterization of this phenomenon are needed to model accurately the future effect of subsidence-related surface damage to postmining land use.
