Abstract: Изобретение относится к горному делу и может быть использовано при подземной разработке газоносных угольных пластов длинными столбами по простиранию с обрушением кровли. Способ заключается в том, что очистной забой проветривают по прямоточной или возвратноточной схеме с отводом части исходящей струи через выработанное пространство с помощью газоотсасывающего вентилятора. При этом в зонах выработанного пространства, прилегающих к сопряжениям очистного забоя с воздухоподающей и воздуховыдающей выработками, по мере подвигания забоя возводят воздухонепроницаемые полосы (ВНП). В зоне сопряжения очистного забоя с воздухоподающей выработкой ВНП возводят вдоль очистного забоя, через расстояние, не превышающее шага посадки непосредственной кровли. В зоне сопряжения очистного забоя с воздуховыдающей выработкой при применении возвратноточной схемы проветривания ВНП возводят аналогично вышеописанному, а при прямоточной схеме проветривания вдоль поддерживаемой воздуховыдающей выработки. ВНП можно создавать путем обработки обрушенных пород вспененными гелеобразующими составами. Технический результат - снижается объем утечек воздуха и возрастает эффективность работы газоотсасывающего вентилятора, снижается вынос метана в призабойное пространство и уменьшаются утечки воздуха. 3 з.п.ф-лы, 2 ил.
