TL;DR: In this paper, the effects of dominant rock properties on cutter performance were analyzed using a triaxial force dynamometer with capacity of 50 tonnes and a data acquisition system, and the results indicated that uniaxial compressive strength among the rock properties investigated is best correlated with the measured cutter performance.

TL;DR: In this article, the penetration rate of percussive blast hole drill was measured in eight rock types at an open pit mine and three motorway sites and the penetration rates were correlated with the rock properties, including uniaxial compressive strength, Brazilian tensile strength, point load strength and Schmidt hammer value.

TL;DR: In this article, a new drillability index for the prediction of the penetration rates of rotary blast hole drill and the mechanical and physical properties of the rock formations was defined from force-indentation curves of indentation tests.

TL;DR: In this article, a simple interpretation method is developed, which quantifies the force- penetration response obtained from indentation tests, and validated by a set of full-scale linear cutting tests using a conical cutter for measuring the cutting performance in relieved and unrelieved conditions, i.e. cutter forces, specific energy, size distribution of rock cuttings.
