The article presents the results of works aiming at comparing a methodology of research on the effect of a pressure impulse coming from detonation of trinitrotoluene – TNT. Within the work, there was studied an influence of the explosive material detonation environment on the pressure impulse. The analysis was carried out with Finite Element Method (FEM). There were selected two cases of mine detonation in the sparse ground (sand) and explosive charge detonation in the tested model of a mine. The model was described in the currently applied standardization regulations utilized for military and exploitation acceptance of special equipment.
