METHOD FOR CONTROL OF EFFICIENCY OF PROTECTIVE EFFECT OF PREVENTIVE MEASURES IN OUTBURST-PRONE COAL SEAMS

摘要

Usage: underground mining of coal seams outburst. SUMMARY OF THE INVENTION: drilled wells in the supra- or undermining ive zone which is not subject to influence by mining, well sealed, t derivatives injection and pumping gas from a gas mixture filtruyuschihs vyde-. l dissolved informative component and determining a time to stabilize it, then the gas permeability coefficient is determined in said adjacent zones (adjacent) layers and with an increase in the gas permeability of 10 times or more compared with the measurement in the unloaded areas protective effect on-railway or part-time work is considered effective. 1 yl.
