Abstract: A new direction of constructing powered roof support for applying the technology of developing thick layers with the manipulated discharge of sub-roof coal on the face conveyor that allows increasing the rock mass flow and reducing the losses and coal ash-contents is offered by the Coal Institute of FRC CCC SB RAS. A discharge window in the form of a chute with the installed manipulated feeder is made in a roof support fencing. The calculations of stress-deformed state of the support unit feeder and side boards of the chute are given. On the bases of the obtained data a quarter scale laboratory model for simulating stress-deformed state of the feeder and a support unit chute for researching the coal discharge process was developed.

Key words: powered roof support manipulated discharge of coal feeder simulation laboratory model
