Computer modeling and analysis of the Greens Creek Mine, Admiralty Island, AK.
Spokane, WA: U.S. Department of the Interior, Bureau of Mines, RI 9530, 1994 Aug; :1-23
The U.S. Bureau of Mines is conducting investigations to improve design methods for mining volcanogenic massive-sulfide- (VMS-) type deposits in environmentally sensitive regions. This study was conducted at the Greens Creek Mine, which is typical of many VMS-type deposits throughout southeast Alaska, and served as a case history for computer modeling and structural analysis. Results indicated that the finite-element design method provided reasonable comparisons with both the anticipated regional stress regime and the measured deformational response of the underground accessways. Investigators concluded that reasonable accuracy can now be expected for stability analyses of proposed mine design scenarios at this mine using the results of this preliminary study.
