<p>Invention refers to mining and can be used for mineral production through wells. The method for increasing in situ rock permeability comprises uncovering a mineral stratum with a well, supplying fluid into the well, impact on the fluid by static pressure as well as by the shock waves of the definite structure with their transfer along the fluid channel into the well with subsequent turning from the wave reflector to the stratum and wave dilatant decompaction of the rocks, at that the impact on the fluid by static pressure and by the shock waves is effected simultaneously, besides, the static pressure value is 1.3 times as much as the value of capillary pressure appearing in the pores the amount of which prevails in size in the rocks decompacted and the shock wave amplitude is chosen as equal or exceeding the compressive or tensile stress which is necessary for running of dilatant decompaction of the rocks. The proposed engineering solution allows to improve efficiency of the process of increasing in situ rock permeability and decompaction, to reduce energy consumption at the work cost reduction.</p> |
