Experimental study of the influence of penetrator shape on fusion drilling efficiency
- Authors:
- Vladimir S. Litvinenko
- G. N. Soloviev
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.

Current state and prospects of geological exploration drilling development
- Authors:
- I. S. Afanasyev
In 1988 more than 25.5 million meters of wells were drilled for solid minerals in our country. Obviously, this was the maximum for all the years of existence of the geological industry, and it is unlikely that such a volume of drilling will be achieved in the future. However, during the period 1968-1990 the volume of geological exploration drilling decreased by almost 3 million meters. What are the main reasons for the decline in drilling?

Calculation of fusion core drilling speed with liquid coolant
- Authors:
- B. B. Kudryashov
- N. G. Menshikov
The energy intensity of fusion ice drilling is many times higher than that of mechanical destruction. A significant advantage of the fusion ice drilling method is the simplicity of design and reliability of thermoelectric drilling shells on a load-carrying cable, so they have been widely used in the domestic practice of studying glaciers and ice sheets with the help of deep boreholes and allowed to achieve record results.
