Abstract
In the mid-1970's in South Africa and Sweden, techniques developed by earthquake seismologists were applied to the study of rock bursts. Recently, developments in microcomputers have made the process of capturing, storing, and analyzing seismic records much easier, e.g., high-speed data acquisition hardware capable of converting incoming analog signals to digital records and high-capacity, high-speed storage devices. The research discussed in this U.S. Bureau of Mines paper utilizes these recent developments in seismology and computer hardware to examine individual rock bursts, determine their source mechanisms, and develop improved control techniques to prevent further occurrences. This research is needed not only to reduce bursting at the depths now being mined, but to enable U.S. mines to supply needed mineral resources from even deeper deposits.
