Feasibility of using self-focusing of uhf electromagnetic waves in breaking dielectric rocks

Soviet mining science Aims and scope

Conclusions

  1. 1.

    The interaction of uhf electromagnetic waves with dielectric rocks can lead to selffocusing of the waves within the rock, causing the development of internal heat sources which have a disruptive effect on the rock.

  2. 2.

    A decrease in the wavelength of the electromagnetic radiation leads to a reduction in the critical dimensions of the internal heat sources necessary for the production of breaking deformations. A rise in the power of the uhf radiation reduces the time taken for the development of the internal heat sources.

  3. 3.

    Further investigations will enable us to elucidate the influence of the composition and structure of the rock on the course of self-focusing, and also the possibility of obtaining controlled self-focusing. Of special interest is the study of the mechanism of formation of plasma, which absorbs the electromagnetic radiation, in the zones of self-focusing.
