Grain size composition and distribution in drill cuttings in the electric impulse destruction of rocks

Abstract

The present studies into the granularity and grain size distribution in drill cuttings after electric impulse destruction of rocks show that the grain size composition and distribution are mostly affected by the interelectrode spacing, energy deposition in the discharge channel and rock strength. The increase in the spacing and strength of rocks raises the share of coarse fraction, while the greater energy deposition results in the higher share of fine fraction.
