The drilling systems, the factors effecting drilling work and the general relations between type of drilling systems and corresponding the property of rock introduced. First, the basic features of rock drilling and the role of drilling work in energy efficiency of mineral industry is generally described. Then the importance of energy concept which is usually expressed in terms of specific energy, and related approaches as well as the related studies are reviewed. The recommendations made for the future research directions to enhance the energy efficiency of drilling operations in mineral industries. The papers included in the review were mainly selected through searches in major abstract databases ofweb of science
