A laboratory crushing apparatus for understanding dynamic rock fragmentation

S. Huang, B. Mohanty

Publisher: International Society for Rock Mechanics and Rock Engineering

Paper presented at the ISRM 2nd International Conference on Rock Dynamics, May 18–19, 2016

Paper Number: ISRM-ROCDYN-2016-12

... ABSTRACT: In rock crushing process, a key goal is understanding of fragmentation behaviour, which could be used to improve productivity and efficiency in mining operations. In this study, the input parameters, such as feed size, output particle size, and the energy expended in the process...

Indentation fragmentation mechanism of anisotropy shale under dynamic and static loads

G. J. Dong, P. Chen, T. S. Ma

Publisher: International Society for Rock Mechanics and Rock Engineering

Paper presented at the ISRM 2nd International Conference on Rock Dynamics, May 18–19, 2016

Paper Number: ISRM-ROCDYN-2016-38

... ABSTRACT: Low Rate Of Penetration (ROP) is one of the key technical difficulties in the anisotropic shales reservoir. Rock fragmentation efficiency is improved under coupled dynamic-static load. A new model for estimating the indentation fragmentation process of shale is developed. The damage...
