Abstract
Abstract
| Outbursts, or the sudden and sometimes catastrophic expulsion of coal and gas into the working area of a coal mine, are a little understood and growing problem. The AE/MS (Acoustic Emission/Microseismic), or rock talk, activity prior to and associated with several outbursts has been recorded using ultrasonic and micro- seismic equipment and has been analyzed by the Bureau of Mines. Analysis of these data indicates that outbursts are comprised of several failures in rapid succession and that anomalous AE/MS data suitable for providing failure warning are generated 15 to 45 minutes prior to the failure. This paper discusses the techniques for recording and analyzing these data and presents sane case histories. |
