ABSTRACT
In given article modern techniques of longwall complexes recovery are considered by the example of Kuzbass coal mines. The structure of time consumption required for longwall face recovery is given. The technique of recovery based on improving the stability of immediate roof, that allows reducing breakage face dead-time duration is recommended.

Keywords: recovery rooms, longwall face, immediate roof, roof caving, front abutment pressure
