A method for dismantling support units wherein one performs support of the roofing of the seam with slabs of support units, preliminarily before dismantling development along dismantling chamber of following section, sequential dismantling of support units under protection of following sections, with its displacement along dismantling chamber by dimension of dismantled support unit. To provide more reliable fixation of roofing of dismantling chamber at most dangerous place of connection of face with mine tunnel due to increase of variants of fixation of the joint for each individual dismantling chamber, depending on mining-geological conditions, before development along dismantling chamber of following section one removes at least one aftermost support unit, and at space released individual support is mounted. |
