In 1972, the Bureau of Mines developed a direct-method test for measuring the gas content of virgin coal core samples for coal mine health and safety considerations. Since that time, approximately 1,500 coal samples from more than 250 coalbeds in 17 States have been collected for gas content determination. The gas content data, when combined with geologic and engineering studies, can be used as a basis for a preliminary estimate of mine ventilation requirements, and to determine if methane drainage in advance of mining should be considered. The data are also critical in delineating coalbed methane resources and in utilization feasibility studies. This report makes the Bureau's extensive data base of gas content data more readily available to the coal and gas industries. The data are presented in tabular form, alphabetically by coalbed name and by State. The components of the total gas content (lost, desorbed, and residual gas) are given, Location (State and county), sample depth, coalbed or formation name, and coal rank are included for geographic and geologic identification.

Coal Geology provides a complete integrated handbook on coal and all its properties, covering the physical and chemical properties of coal as well as coal petrology. It describes the age and occurence of coal; coal sampling and analysis; coal exploration; geophysics and hydrogeology of coal and coal mining techniques. It also discusses environmental concerns and computer technology, and includes an update on global coal reserves and production figures. First reference book to cover all aspects of coal geology in one volume Includes current thinking on environmental issues Presents a useful synopsis of the alternative uses of coal as a fuel Contains the distribution and reserves of coal deposits worldwide Offers a summary of the use of computing in coal studies, as well as coal sales and marketing opportunities Includes International Standards listings This up-to-date handbook successfully bridges the gap between academic aspects of coal geology and the practical role of geology in the coal industry and will be invaluable for all professionals and students in coal geology, geotechnical and mining engineering, and environmental science.

Genre: Nature
ISBN:

Contains background information on the chemical and physical properties of coal--its nature, origins, various types and classification on a global basis. Highlights currently known geographical distribution of coals, their ages, recent production figures and major exporter countries. Essential exploration techniques and procedures, together with standards of geological practice, are described. The geologist's role in data collection, sampling, the calculation of resources/reserves, geotechnical studies as well as the preparation of geological reports are examined.
