Abstract

The discrete element code UDEC is used to simulate the response of fractured rock masses due to a small-scale field explosion. The UDEC modeling includes three stages. First, the in situ stress is calculated by assuming that the rock is elastic and only overburden gravity load with no tectonic stress is considered. Second, the stress redistribution due to the drilling of the charge chamber is computed. Finally, the dynamic response of the rock masses due to the explosion is modeled. The modeling results are compared with the test results and empirical formulas.
