Abstract Stress conditions around deep underground mine openings can significantly influence rock fragmentation and stability, and thus the cuttability of the targeted rock. In this study, rock breakage experiments and associated regression analyses indicate nonlinear rock cuttabilities (decreasing followed by increasing) with increases in the differences between biaxial confining stresses and the values of uniaxial confining stresses. Rock breakages were found to be efficient and safe under low...

Abstract Innovations of mining technologies were proposed by beneficial utilizations of unfavorable factors such as high geostress, high geotemperature and high mining depth to achieve green mining as mining depth increases inevitably. Cuttability of deep hard rock was investigated by experimental and regressed analyses to find the reasonable stress adjustment method to improve non-explosive mechanized fragmentation for hard ore-rock. A non-explosive mechanized and intellectualized mining method...
