Full TextAbstract
In order to optimizing of the blasting operations,we need to evaluate rock mass properties in studying mines. For this purpose, three methods of line mapping, seismic refraction method and experimental tests were used. Properties of 7730 discontinuities were measured at 1780 meters long of the scanline. To determine Vpf (the velocity of longitudinal waves in rock mass) 73 seismic profile was run at 1771 meters long of seismic profiles. Also for characterization of intact rock such as UCS (uniaxial compressive strength), UTS (uniaxial tensile strength), density, Vpl(the velocity of longitudinal waves in intact rock) and Schmidt hardness, the standard tests were used. For Engineering assessment, rock mass was classified according to the RMR classification system. Finally, in addition to analysis of each parameter and present the results for studying mines, equations to estimate RMR based on the results of seismic survey and relationships to predict some properties of intact rock were developed.
