Sound wave theory was used for qualitative pattern of seismic wave distribution around blasting. Results show changing of seismic waves from round to elliptical shape during distribution through rock massif with cracks.

Parameters of power and geometrical similarity are received for these explosions, have allowed to express
characteristics of seismic waves depending on weight of a charge and distance to an explosion place. Last are simulated and used for delimitation of carrying over of the gas pipeline located near to the future zone of carrying out of explosive works of under construction Eristovsky open-cast mine, which on mining and geological conditions, seismic properties composing its breeds and technologies of explosive works similar with the operating.

The paper considers the problem of defining the influence of actual conditions of elastic deformations in
seismic waves (in the conditions of changing tensions under uniform compression in anisotropic mediums and in
dynamic mode of load application) on the speed of body seismic waves.
