Geologic Factors Affecting the Mining of the Lower Kittanning Coalbed in Cambria County, Pennsylvania.
13th Ann Meeting Ne Sect Geol Soc of Am Boston Ma 1978 Abs 1978 10(2):1 pages
Mining of the Lower Kittanning coalbed is affected by geologic factors that influence the occurrence of "wants" and roof falls. Geologic conditions encountered in past mining and projects of geologic trends established from standard mapping techniques were extrapolated to unmined areas. Two types of "wants" (erosional and depositional) are discussed.
