The U.S. Bureau of Mines investigated the feasibility of acoustic emission monitoring for use in determining the stability of dump points of mine stockpiles and waste dumps. A small-scale test facility made of a sand and gravel mixture was constructed for testing model dump points. Loading was provided by a rubber-tired caster mounted on a shaft that could move both vertically and horizontally by hydraulic cylinders. The acoustic emissions generated in the soil were picked up by piezoelectric accelerometers, and the outputs were saved with a digital waveform recorder. The acceleration data were analyzed by looking at the amplitudes, ring-down count rates, energy rates, and frequency spectra. Stationary load tests were run near the slope edge (an unstable loading) and on stable soil away from the edge. The results of dynamic load tests simulating a truck backing to the slope edge were dependent on waveguide location. Most of the signals detected by the transducers appear to be coming from the tire on the soil surface and not the instability of the slope. Acoustic emission monitoring of dump points does not appear to be a viable method, given the limitations and difficulties encountered in this study.
