Abstract
Based on the analysis of qualitative interaction between rocks and a rock-breaking tool, a new coefficient of the tool efficiency is proposed. This coefficient makes it possible to estimate the quality of the tool impact on broken rocks and to predict energy input of rock breaking and, consequently, productivity of mining machines in specific geotechnical conditions.
