Abstract
Under the efficiency of the process of drilling rocks by fusion should be understood not only the rate of deepening into the rock, but also such factors as the diameter of the well, its ratio with the diameter of the penetrator, the amount of melt formed per unit time, the thickness of vitrified melt on the walls of the well, its strength, the specific energyb consumption per unit of penetration and many other.
