The difficulties of unloading the adfreezed coal from the rail carriages in winter constantly lead to financial losses estimated up to hundreds of millions roubles. Therefore, we suggest using the electrohydropulse effect to restore the looseness. By carrying out joint scientific research, we examined the electrical and hydrodynamic processes in the fluid and the mechanical processes in the solid substance. In this paper we give a mathematical model of the electrohydropulse process in the condition of compressing the fluid and deforming the discharge cavity. Moreover, we estimated the obtained pressure in the adfreezed coal and established the quantitative and qualitative interconnection between the electrical parameters of the discharge and the fluid pressure in the spherical cavity.
