Abstract
This Bureau of Mines report presents the results of a microseismic study conducted in the climax block cave mine at climax, Colorado. Rock noises created by caving were monitored and their sources located during a 3-month period. A planar array of seven accelerometers, located above the block of ore being caved, detected the rock noise. A computer was used to calculate the location of the microseismic activity, using a traveltime difference method. The accuracy of these locations was estimated to be +/-20 feet. An analysis of the data taken during the recording period showed a concentration of microseismic events located in the wall of the cave panel. This concentration of events was found to occur in a "high-silica" geologic formation that cut across the caving panel approximately 200 feet behind the undercut.
