Supporting members come in the form of metal rods which are combined in groups of 3-5 members with joining of their ends brought out into dismantling chamber with the use of flexible tie-rod. Each group of supporting members depending on mining and technical conditions is extracted together with dismantled section of support or right after dismantling of the whole powered support.
