Abstract
Abandoned mines are not likely cause of emissions during mining &bull Coal has enough permeability but is water saturated. Thus, gas can escape only during mining &bull Calculated gas in place and specific emissions suggest that GIP of only Lower Kittanning coal should result in lower specific emissions &bull Groundwater level and its correlogram analyses indicated that general flow direction was towards the southeast and the active workings. &bull Modeling the water head indicated that it was high enough to include all Allegheny Group formations within the saturated zone. &bull Computations of flow gradients showed that the groundwater flows towards Yellow Creek and Two Lick Creek as discharge locations in this region.
