FIELD: mining industry; applicable in long face mining of outburst-prone districts of potassium seams by hydraulically powders mining complexes. SUBSTANCE: method includes starting of face conveyor, coating of conveyor in line of initiating cut with flame-suppressing mixture, initiating of outburst by blast and discharge of salt-gas flow. The distinguishing feature of the method consists in that before starting the conveyor, installed on haulage drift is thrower, and after starting, conveyor is coated with salt culm which serves as flame suppressing mixture. After blast, products are directed by thrower to worked-out space of reclaimed drift. EFFECT: higher efficiency. 2 dwg
