Abstract
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.
