METHOD FOR PRODUCING VIBRATION EFFECT ON ROCKS

摘要

The invention relates to mining and can be used for hardening or softening of rocks in the array. The purpose of the invention - expanding field of application of the method due to the possibility to produce various effects with increasing exposure efficiency. In massif drilled working well (C), it equips and determining a fundamental frequency of a vibration (WB) array. At a distance of 5/3 wavelength of the fundamental frequency from the working C. drilled additional C is placed in the air gun subarray are non-explosive and excite them identical in waveform. WB to provide an array of stages. The first stage in the frequency range 60-1500 Hz is supplied to the working fluid C with the addition of silica sand with particle size 0.03-0.15 mm, and 2% surfactant. In the second stage B is carried out for a time, at which the compression deformation in the array changes by deformation stretching. In the third step proceeds to the WB frequency of 150 Hz, is produced in the rock m pumping razuprochn constituents or reinforcing solutions and VB performed to achieve the desired effect. 2 ZP f-ly. 1 yl. te
