Изобретение относится к горной промышленности и может быть использовано при разработке угольных месторождений. Многолетнемерзлый угольный массив в естественных условиях водонепроницаем, что затрудняет применение предварительного увлажнения пластов и снижает его эффективность в обеспечении уменьшения выхода пыли при добыче и переработке угля. Для восстановления фильтрационной способности многолетнемерзлого угольного массива и возможности поглощения им увлажняющей жидкости с равномерной пропиткой предлагается непосредственно перед нагнетанием воды в пласт проводить подготовку угля, заключающуюся в избирательном протаивании и освобождении от ледяных включений мелких трещин и пор в массиве с сохранением льда в крупных трещинах.The invention relates to the mining industry and can be used in the development of coal deposits. The permafrost coal mass is waterproof in natural conditions, which complicates the use of preliminary wetting of the seams and reduces its effectiveness in ensuring a reduction in dust yield during coal mining and processing. In order to restore the filtering ability of the permafrost coal mass and the possibility of absorbing a moisturizing liquid with uniform impregnation by it, it is proposed to conduct coal preparation, which consists in the selective thawing and release of small cracks and pores in the massif from ice inclusions with the preservation of ice in large cracks immediately before injection of water into the formation.
