This paper introduces the use of stochastic methods in computing the dynamic fracture strength of rock due to blasting and compares the results with a deterministic method. Dynamic fracture strength is a function of rock properties density, p-wave velocity, s-wave velocity and dynamic tensile strength. Generated sample functions of these variables are formed by one-dimensional random processes. Stochastic methodology computes the dynamic fracture strength by incorporating the variations in these random variables. It has been shown that the maximum stress obtained by the analysis utilizing stochastic methodology are greater than the deterministic method. The variation of the explosive type changes the dynamic fracture strength of rock.
