METHOD OF REDUCTION OF OUTBURST HAZARD OF COALS AND ROCKS

摘要

Usage: gornodobyvayuscha industry, underground mining, abatement of coal, rock and gas. SUMMARY OF THE INVENTION: In an array of rocks drilled wells, is set in vibrations which sources is injected into wells 2-3% surfactants solution together with the oscillation excitation frequency 60-1500 Hz and then exposed to an array of electromagnetic wobbles with a frequency range of 0.01-100 MHz, exposure is carried out until gas evolution before the drop of the initial level, and then injected into the array the hot solutions of sodium hydroxide or sodium hydroxide with methanol and affect oscillatory E with a frequency equal to the natural frequency of oscillation of the array, until the voltages constituting no more than 0.5 times the magnitude of the destructive stresses. 2 yl. .
