METHOD OF METHANE EXTRACTION FROM COAL SEAM |
摘要 |
FIELD: mining.SUBSTANCE: invention relates to mining and can be used for methane production from coal seams. Proposed method comprises drilling or opening of used vertical well at methane-coal bed and determination of seam depth in well cross-section. Coal grade composition is defined and short high-pressure directed pulses source is fitted via working interval of vertical well in said methane-coal bed. Said bed is subjected to the effects of energy of plasma generated by the blast of calibrated metallic conductor as intermittent directed short high-pressure pulses. The number of high-pressure pulses and duration of said effects in interval of methane-coal bed is defined by bed depth in well cross-section and coal grade composition.EFFECT: higher efficiency of methane production, lower costs and higher safety.1 dwg |
