This publication provides a comprehensive summary of Indiana coal resources, coal characteristics, and current and potential use of Indiana coal, including a review of all the publically available data, as well as new data obtained and processed for the purpose of this project. This report provides the most up-to-date detailed evaluation of coal resources, both the original resource and coal available for mining. In addition to the previously evaluated resources of the Springfield, Danville, and the Seelyville coals, new GIS-based valuations are provided for the Hymera, Houchin Creek, Survant, and Colchester coals. The coal quality of major coal beds in Indiana is discussed and maps of sulfur, ash, and heating value are provided. Summaries of 35 trace elements are given and mercury, selenium, arsenic, and chlorine are discussed in more detail. Other aspects include coalbed methane potential (CBM), CO2 sequestration, characteristics of limestone and dolomite for flue gas desulfurization (FGD), and the production and use of coal combustion products (CCP).
