В экспериментальных и теоретических исследованиях установлено, что микроструктура угля в масштабе нескольких микрон определяет возможность участия связанного метана в динамическом разрушении угля. В отличие от действия свободного метана, изначально находящегося в угольном пласте, разрушение угля за счет связанного метана неизбежно должно перейти на более крупные масштабные уровни. Детали состояния связанного метана в угле (сорбированный или растворенный метан) не имеют большого значения для газодинамического разрушения угля. Проведенные исследования подтверждают вывод о том, что анализ структуры нарушенности угля на микроуровне может быть эффективным методом прогноза выбросов угля и газа в угольных пластах.
