Abstract: It’s given a generalized foreign and Russian experience of entry into the previously prepared dismantling production. Research shows the characteristic parameters of the behavior of the roof in emergency entrances. Roof collapse at the entrance to the clearing mechanized complex in a previously prepared dismantling production typed. On the example of extraction pillar 5a-10-18 of Raspadskaja mine it is considered the formation of stress-strain state in the vicinity of previously prepared dismantling production. It was presented simulation of conditions of entry into the heavy roof. Determine the expected load on the bolting and a hundred-stationary- bolting installed in dismantling production.

Key words: dismantling production clearing mechanized complex supporting pillar distribution of abutment pressure stress-strain state roof bolting
