METHOD OF UNEXPLOSIVE ACTION ON GROUND AT TIME OF SEISMIC EXPLORATION Russian patent published in 2009 - IPC G01V1/02 

FIELD: mining.

SUBSTANCE: initial direction of the impact force moving in the vertical direction of a mass weight is chosen opposite in reference to the ground, then its movement direction is changed to the opposite with time delay as related to the time of the ground flow implied by Hooke's law and the value of the impact force and the square of foot plate of the radiation source is selected so to provide specific pressure on the ground that will not exceed the ground strength limit from the correlation σ=ρυ_pυ_g, where ρ is consistency of the ground; υ_p is seismic velocity in the ground, υ_g is rate of ground deformation.

EFFECT: improved effectiveness of the unexplosive action on the ground with a simultaneous reduction in a ground destructive effect.
