METHOD OF PREPARING ROCK MATERIAL FOR RECESS USING LASER EXPOSURE AND AUTOMATED SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC E21C41/26 E21C37/16 

FIELD: mining.

SUBSTANCE: method is performed using the automated system which comprises a laser device with the possibility of longitudinal displacement and is provided with a damper platform placed on the surface miner frame and pivotally connected to the frame of the laser device. The laser device is placed on the frame guides with the ability to move longitudinally along the guides on the rolling bearings using the drive connected with the automatic control unit, and is made in the form of a cassette with fibre-optic emitters placed along the moving direction of the surface miner.

EFFECT: improved technological efficiency due to forming in the surface layer of the processed areas of zones with overlapping of laser slots, providing high concentration of stresses, alternating loads and deformation during laser processing of significant surface; performance improvement of process of destruction, disintegration and decrease in the volume of fraction requiring additional subsequent crushing due to combining the process of cutting slits and layers-strip cutting of rock materials by surface miners, and providing environmental safety.
