Stability of rock pillars between penetrated rock-breaking indenters
Strength of Materials, 1990The formation of spalls with penetration of different types of indenters into rock is modeled by the finite-element method. Conditions in which there is chipping of rock pillars between penetrated indenters are investigated.

THE EFFECT OF ROCK BIT CUTTING STRUCTURE ON ROCK BREAKING EFFICIENCY
Proceedings of International Meeting on Petroleum Engineering, 1986ABSTRACT A study of the effect of rock bit cutting structure on rock breaking efficiency was made with full scale bits for soft to medium formations on a laboratory testing rig. An analysis of the relationship between rock breakage and cutting structure based on the drilling rate, bottom hole pattern and operating parameters revealed the
