Abstract
In order to determine if mine rollers maintain their effectiveness with increased velocity, test rollers were passed over buried pressure cells on a track designed to produce highly repeatable results. Passes were conducted at speeds up to 40km/h and repeated with four different sizes of test rollers. In total, over 200 repetitions were performed. The raw pressure data was analyzed in terms of peak pressure and impulse. It was found that the effects of increased speed are a slight increase in average peak pressure, significant reduction in impulse values, increase in bouncing/vibration, and decreased reliability. Narrow rollers produced higher pressures than wider rollers, but were also observed to bounce more. Based on these results it is recommended that mine rollers should be used at low speeds, and should be designed to minimize the amount of bouncing and vibration.
