18th U.S. Oil Shale Symposium, Grand Junction, Colorado, April 1985 Author: T. W. Gulliver (AAI) Dissolution of salts in the Piceance Creek Basin oil shales has lead to considerable collapse. Fracture systems affecting dissolution at depth show visible lineaments. Remote sensing, hand in hand with drill hole data, allows interpretation of solution collapse and modeling [...]
2004 SME Annual Meeting & Exhibit, February 23–25, Denver, ColoradoAuthors: J. F. T. Agapito and L. J. Gilbride (AAI), and K. Hollberg (OCI Wyoming, LP) Room-and-pillar mining at the Big Island Mine uses narrow, yield (i.e., load transferring) pillars to achieve high resource recovery and productivity. Two flat-lying 3- to 3½-meter (10- to 11½-ft) seams [...]
Rock Mechanics for Industry, 37th U.S. Rock Mechanics Symposium, Vail, Colorado, 6–9 June 1999Authors: R. R. Goodrich (AAI), W. K. Sorensen (Canyon Fuel Company), J. F. T. Agapito (AAI), and J. Black (Canyon Fuel Company) Canyon Fuel Company operates the SUFCO coal mine located in the southern Wasatch Plateau Coal Field approximately 48 km (30 [...]
22nd International Conference on Ground Control in Mining, Morgantown, West Virginia, 5–7 August 2003 Author: F. S. Kendorski (AAI) A longwall coal mine in Appalachia about 1,500 ft deep encountered a fault while developing a new longwall panel. The fault extended from mining depth to the surface near a secondary road and drainage. The fault [...]
Mining Engineering, July 1997 Authors: J. F. T. Agapito and R. R. Goodrich (AAI) and M. Moon (Energy West Mining Co.) Experience at Energy West Mines in the Wasatch Plateau Coal Field, Utah, has shown that longwall face bursts occur mostly near the tailgate when extracting the third adjacent longwall in a panel section where [...]
