Claims (5)

1. Способ дегазации угольного пласта, включающий бурение скважины, отсос через нее дренирующегося газа, с проведением работ по интенсификации его дебита, путем рыхления прилегающего к скважине массива посредством ввода в массив газогенерирующего материала, отличающийся тем, что для рыхления прилегающего к скважине массива его пропитывают жидким диоксидом углерода, после чего инициируют переход жидкого диоксида углерода в газообразное состояние подачей в скважину горячего газа с температурой, обеспечивающей переход жидкого диоксида углерода в газообразное состояние, и последующим отсосом газообразных продуктов из скважины.1. A method of degassing a coal seam, including drilling a well, sucking drainage gas through it, carrying out work to intensify its flow rate, by loosening the array adjacent to the well by introducing gas generating material into the array, characterized in that it is impregnated to loosen the array adjacent to the well liquid carbon dioxide, after which they initiate the transition of liquid carbon dioxide to a gaseous state by supplying hot gas to the well with a temperature that ensures the transition of liquid dioxide leroda in the gaseous state, and subsequent suction of gaseous products from the well. 2. Способ по п.1, отличающийся тем, что пропитку массива жидким диоксидом углерода ведут с напором, соответствующим давлению гидроразрыва материала его слагающего.2. The method according to claim 1, characterized in that the array is impregnated with liquid carbon dioxide with a pressure corresponding to the fracturing pressure of the component material. 3. Способ по п.1, отличающийся тем, что в жидкий диоксид углерода вводят расклинивающие агенты, например тонкодисперсный материал, твердость которого выше твердости материала, слагающего массив.3. The method according to claim 1, characterized in that proppants, for example finely dispersed material, the hardness of which is higher than the hardness of the material composing the array, are introduced into liquid carbon dioxide. 4. Способ по п.1, отличающийся тем, что в качестве горячих газов используют газообразные продукты сжигания горючих материалов.4. The method according to claim 1, characterized in that as the hot gases use gaseous products of the combustion of combustible materials. 5. Способ по п.1, отличающийся тем, что из газообразных продуктов, извлеченных из скважины, отбирают диоксид углерода.5. The method according to claim 1, characterized in that carbon dioxide is taken from the gaseous products extracted from the well.
