CONTROL METHOD OF LASER TREATMENT OF ROCK MATERIAL OF VARIABLE RIGIDITY AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC E21C41/26 B23K26/00 

FIELD: mining.

SUBSTANCE: control method comprises control of the intensity of the high temperature thermodynamic laser irradiation to the area of the laser radiation, regulation of change of the wavefront of the laser radiation, control of milling cutting force P, the parameters of the rock material rigidity f through the registration sensor of the rock material rigidity, mounted on the frame of fibre optic laser emitter, the speed control of movement of the surface miner V_ki, introduction to program of algorithm of calculation of the wavefront of laser radiation power W, depending on the parameters of rock material rigidity f and the approach increment of fibre optic emitters l_i based on the equation.

EFFECT: invention enables to improve the efficiency of management of technological preparation for excavation of rock material and provides remote control of destruction of rock material.
