Rockburst monitoring at the Sunshine Mine, Kellogg, Idaho
The rockburst monitoring system at the Sunshine Mine has recently been improved to increase the certainty of burst locations and to output location results in a manner amenable to easy interpretation. Three methods of location calculation were used: a computer code provided with the hardware in-place (the MP-250), a code based on the least-squares method (Blake et al, 1974), and a nonlinear iterative code written by the principal author. The more accurate locations are given by the latter two codes, but still are only correct to within about 100 ft. This error is due to uncertainties introduced by the geologic and mining variations versus the assumptions made in the location codes. Software was written to make two-dimensional plots of burst location by level, so management could monitor problems easily. 8 refs., 5 figs.
