Аннотация


В угольных шахтах, подверженных камнепадам, высокопрочная кровля усиливает шахтное давление и динамические воздействия. Традиционные методы снижения подземного давления, такие как бурение скважин и взрыв угольных пластов, обеспечивают лишь локальное ослабление. Используя теоретический анализ и численное моделирование поэтапного разрыва пласта в горизонтальных скважинах,
были определены оптимальные параметры разрыва пласта для сброса давления в угольной шахте. При высоте разрыва 20 м и длине сегмента 50 м трещиноватая порода может эффективно поглощать энергию удара и снижать риск обвалов, эффективно поддерживая стабильность инженерных сооружений.
