This report is the user's manual for the coal loss calculation model computer program. The study undertook the development and implementation of a methodology for estimating the impact of coal seam interaction on the eastern bituminous underground reserve base as published in Bureau of Mines IC 8655. The effects of previous mining in multiple coal seam areas on currently mined and reserve seams are predicted as a percentage coal loss by an engineering assessment model called the coal loss calculation model. The model utilizes 12 input variables easily derivable from mine maps or other existing data sources and calculates the effects of subsidence and high stress due to remnant pillars in the previously mined seam. A derivative map showing the areas of commonality within the eastern bituminous coal region serves as the basis for implementation of the coal loss calculation model. The model was developed and tested using data from four coal mines in western Pennsylvania and southern West Virginia.
