Abstract
Coal seams approximately 7, 9, and 20 feet thick at depths of 250, 600, and 1,000 feet were detected using high resolution seismic reflection techniques. Investigation of seismic profiles indicates that good data are required to delineate faulting with only 20 feet of throw but that faulting with 20 feet of vertical displacement can be detected with poor data. Data acquired from dynamite charges fired in water saturated media were clearly superior to that acquired using charges dry tamped in 10- and 20-foot holes.
