, Southfield Mine) This paper presents the results of stress measurements, underground observations, and stability monitoring in a southern Colorado mine. The objective of the program... was to assess the causes for panel stability problems and to develop a mine layout design to improve ground conditions. This geotechnical program was implemented in cooperation... with the U.S. Bureau of Mines (USBM). It consisted of laboratory mechanical property testing, overcoring stress determination at two sites, underground observations/convergence...
