The advancing oil shale mining technology program is part of the Bureau's energy research and development program which began in 1974. Objectives are to develop, test, demonstrate, and transfer to industry, improved low-cost mining and waste management methods. The progam is divided into background or baseline studies, and development and demonstration. A pilot demonstration mine is planned for full-scale testing of mining methods and equipment. An exploration program is underway to select a site for the demonstration mine. This entails studies of the geology and hydrology of the Piceance Creek Basin in Colorado, core drilling, and testing. The U.S. Geological Survey has worked with the Bureau on site selection. Results of the program are described and geological and hydrologic data are presented.
