Mining is basic in the process of exploitation of mineral raw materials, whether it is a surface or underground mines. Separate section is the special blasting which must ensure strict, advance superiors conditions. Success in performed blasting depends on the applied method, the rocky massif and quantity of explosives. To determine the method for blasting and the quantity of explosive in the blast holes, it is necessary to know the mechanical properties of the ground: direction of foliation, degree of cracking, Jung modulus of elasticity and other parameters which are used for mathematical modeling to define the position of the blast holes and the optimal quantity of explosive in them. As a proper geophysical method for defining the mechanical properties of the rock complex is seismic method which gave all relevant parameters for successful blasting. Seismic method could be useful applied in defining the explosion zones: zone of thermal influence, internal plastic zone and external plastic zone. In the paper, briefly, will be presented seismic method and the mechanical parameters derived from investigation.
