Abstract: Изобретение относится к горному делу и может быть использовано при подземной разработке мощных пологих пластов полезных ископаемых. Способ разработки мощного пологого пласта полезного ископаемого включает разделение пласта на панели, а в пределах панели на два слоя, параллельные плоскостям напластования пород, подготовку слоев к отработке путем проведения подготовительных выработок, последовательную отработку слоев в нисходящем порядке лавами при отработке верхней лавой в направлении к границе панели, а нижней лавой в противоположном направлении. Подготовительные выработки - вентиляционный и откаточный штреки используют при отработке верхнего и нижнего слоев и проводят на соответствующих концевых участках лавы на расстоянии, которое не меньше ширины защитной зоны и высотой от почвы нижнего слоя до почвы верхнего слоя. Вентиляционный и откаточный штреки проходят проходческим комбайном в процессе отработки верхней лавы при синхронизированных перемещениях комбайнов и лавы. Над ними создают защитные бутовые перекрытия, которые формируют путем замётывания породы, которую получают при проходке подготовительных выработок роторными метательными установками, которыми снабжены проходческие комбайны. Предварительно производят крепление подготовительных выработок рамами из специального взаимозаменяемого профиля (СВП) со сплошной затяжкой рам полимерной сеткой и полиэтиленовой плёнкой. Техническим результатом является повышение эффективности добычи путем сокращения количества подготовительных выработок за счет их повторного использования при отработке обоих слоев и повышения извлекаемости полезного ископаемого за счёт сохранения одинаковой длины лав на обоих слоях. 8 ил.
