Abstract
Method is proposed for temporary fixation of weak rocks. It includes covering rocks of the working with screens, with fixation of working rock massif with anchors and keeping rock massif due to thrust force between the screens and the working. Between the casing and the rock massif in ceiling section one additionally places soft shells, those are filled with air and form initial thrust at opened section of working.
