The U.S. Geological Survey's National Coal Resources Data System comes with an interactive map that provides a huge amount of information on the distribution, thickness, and classification of coal in the United States.
The interactive map contains over 250,000 data points, each typically representing a core sample, drill hole, or driller's log in a specific location. You can use the "Filter" tool to focus in on specific areas, or on data collected by specific organizations. Commonly available data include:
The Society for Organic Petrology (TSOP) is accepting applications for the Spackman Award. Students seeking an advanced degree in organic petrology are encouraged to apply by May 31, 2017. Applicants' research must demonstrate the utility and significance of organic petrology (which includes coal petrology, kerogen petrology, organic geochemistry and related disciplines) in solving the thesis problem.
The West Virginia Geological and Economic Survey provides an interactive map of underground and surface coal mining activity in West Virginia. The map shows areas of active and historical coal mining in both underground and surface mines, with separate colors for auger and highwall mining.
The Utah Geological Survey has produced an interactive map showing the locations of more than 450 abandoned coal mines in Utah. For over half of these, detailed maps of the individual mines are available for download and further use.
