Rock hardness measurement

Abstract

A method of facilitating hardness measurement of a rock sample involves receiving force information representing forces applied to the rock sample during roll crushing, determining size information representing a size of the rock sample, and determining, based on at least the force information and the size information, at least one hardness parameter representing hardness of the rock sample. A method of facilitating hardness measurement of a rock sample from a drill core involves receiving force information representing forces applied to the rock sample during roll crushing of the rock sample, determining, based on at least the force information, at least one hardness parameter representing hardness of the rock sample, and associating the at least one hardness parameter with at least one location from which the rock sample was extracted. Other apparatuses, methods, systems, and computer-readable media are provided.
