Computer-Implemented Coalbed Methane Data Base ? Objective

Provide a coalbed methane data source for industry use in mine planning. Approach Coalbed methane data have keen collected and formatted into a computer implemented data base with software developed for storage, retrieval, and generating files of selected data in response to information requests and for statistical analysis of relationships among various coal parameters. How It Works Coalbed methane data is obtained by the Bureau's direct method test on exploration coal cores. The test involves sealing fresh coal cores in desorption canisters and periodically bleeding the gas into a water-filled, graduated cylinder to measure the volume of gas released. Coalbed methane data collected over the past 9 years have been entered into a computer-implemented data base for efficient retrieval and statistical analysis. Data base processing is accomplished with a commercially available storage, sorting, retrieval, and report writing software package (Datatrieve 11). Information requests from the coal industry are processed with the system, and the data in the desired output format am printed and forwarded to the requestor. Information such as coalbed name, location (state and county), depth of sample, gas content, and coal rank are available from the system. The data can be used for
