Abstract

The optimal cost of blasting is a major factor in the surface mining industry and must be addressed properly. The project will include the variability of components of blast design, such as change in azimuth of the holes intended for blasting to reduce explosive consumption and have a major role in controlling ground vibrations; pattern of holes (diameter of holes); electric and non-electric initiation; toe burden analysis; type of explosive used (slurry and ANFO); and adopting an efficient design by mathematical cost analysis using O-Pitblast software. The damage to temporary structures in surface mining that are located within close proximity of blasting faces is a serious problem and has to be countered using an alternating blast design in correspondence to the permissible Post-Production Verification (PPV) that a structure can withstand. The estimation of the PPV graph using seismographic data of the face must comply with different ground vibration equations to check whether the predicted model of blasting is up to safety norms and the demarking of the blasting zone.
