Abstract : Several calculations of the Mineral Rock event (which duplicated MINE ORE) were performed on Physics International's ELK code. Each of the calculations utilized a different, plausible model of in-situ rock. Peak displacements and velocity histories were compared with data, and with a previous calculation which used a relatively strong rock model. All of the models used showed discrepancies with the experimental data. Agreement between calculated and measured displacements is, however, improved over previous calculations. (Author)
