FIELD: road building. SUBSTANCE: method provides well drilling, location of non-explosive pneumatic sources oriented towards action of maximum head stress. Elastic oscillations are excited within 60 1500 Hz in conjunction with pumping unhardening solutions and generation vibration action, which are generated within time, when tensile stress in changed with compressing stress. Then frequency of liquid pumping into the well of hydraulic fracture is used and vibration exposure is applied up to achieving positive effect. EFFECT: decreased power consumption. 5 cl, 2 dwg
