Rock Burst Control Research by the Us Bureau of Mines.

Although rock burst research has been in progress for half a century, it has been only in the last few years that significant gains have been made. Such gains are attributable almost entirely to advances in computerized numerical modeling, improvements in measuring and understanding rock mass properties, and the development of new instruments to monitor acoustic emissions. With continued developments in these areas, significant progress will be made over the next 10 years in determining the source mechanisms of rock bursts, their exact causes, and the types of damaging shock waves generated. Calibrated computer models based on accurate descriptions of rock properties and geologic structure will help pinpoint areas of potential bursting, and new digital macroseismic and microseismic systems will help identify these potential burst areas. With this information, engineering decisions can be made as to mine layout, advance rate, support requirements, and needed control measures. Where control measures are not possible, mining methods that remove the miner from burst-prone areas or afford protection can be implemented. Robots or remote-controlled mining are possible answers to this problem, and designs for such automated systems are already on the drawing board. The ability to analyze, construct, and maintain cost-effective control and abatement systems for rock bursting will greatly enhance the productivity and safety of deep mining in the United States.
