International Journal of Mining Engineering, 3:195–213, 1985 Authors: J. F. T. Agapito, and S. J. Mitchell (AAI), and L. A. Weakly (Exxon Company) Stability in Exxon’s Colony Pilot Mine in the Piceance Creek Basin, Colorado, has been monitored by periodic pillar stress determinations and roof-to-floor convergence measurements since 1971. Pillar failure has caused marginal stability [...]
17th U.S. Symposium on Rock Mechanics, Snowbird, Utah, 1976 Authors: J. F. T. Agapito (AAI) and J. B. Page This paper describes part of a geotechnical study based on stress determinations and convergence measurements conducted to assess the long-term stability of an experimental room-and-pillar oil shale mine. A rock mechanics program was initiated in 1971 [...]
19th U.S. Rock Mechanics Symposium, University of Nevada, Reno, Nevada, May 1978Authors: J. F. T. Agapito (AAI), and J. W. Bennett and J. P. Hunter (Stauffer Chemical Company of Wyoming) This paper describes part of a rock mechanics program being conducted at the Big Island Mine of Stauffer Chemical Company of Wyoming. The program objective [...]
25th U.S. Symposium on Rock Mechanics, Evanston, Illinois, 1984 Authors: H. Maleki (AAI), W. Hustrulid (Colorado School of Mines), and D. Johnson (Utah Fuel Company) Gob pressure measurements were made in a Western U.S. coal mine as part of a long-term program to evaluate cave progress and to determine the influence of geological discontinuities on [...]
28th U.S. Symposium on Rock Mechanics, Tucson, Arizona, 29 June–1 July 1987 Authors: J. F. T. Agapito (AAI) and D. R. Shoemaker (Molycorp, Inc.) Evaluation of ground stability and support requirements during block caving operations at Molycorp’s Questa Mine was conducted with the help of a simple rock mechanics program consisting of underground mapping and [...]
