FIELD: mining.
SUBSTANCE: method of working crossing by working face includes the following stages: performance of two extraction galleries and working, passed between them with formation footwalling; formation of artificial ground with floor installation for equipment movement and working crossing by working face with formation footwalling. Note that pneumatic cogs are delivered into the said working between extraction gates on which U-shaped wooden floor is laid. As working face approaches the working pneumatic cogs are filled with compressed air and the floor is lifted, after the working face crosses the working the pneumatic cogs are unloaded, the floor is descended to the ground of working and pneumatic cogs are extracted into extraction working.
EFFECT: increase of artificial ground creation efficiency in the working crossed by working face.
