ABSTRACT

ABSTRACT: A small-scale field explosion test was conducted in granite to investigate the dynamic response of jointed rock masses under explosion loads. The test is modeled by using the discrete element code, 3DEC, an extension of the Universal Distinct Element Code (UDEC) from two-dimensional to three-dimensional analyses. The 3DEC 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.
