Central...; Abstract: For the purpose of describing the deformation characteristics of rocks, the effect of volume changes on mechanical properties of rocks should......
rocks with the use of a relief method of annular hole-drilling was studied by numerical analysis. The stress relief process by hole-drilling was then simulated with the use of finite element method... core surface in the relief measurement process. Finally, a non-complete relief method of annular hole-drilling for measuring surface stress in surrounding rocks is proposed and the procedure......
Specific energy optimization in sawing of rocks using Taguchi approachIzzet Karakurt(Department of Mining Engineering, Karadeniz Technical University, Trabzon 61080, Turkey)Abstract:This work aims at selecting optimal operating variables to obtain the minimum specific energy (SE) in sawing of rocks. A particular granite was sampled and sawn by a fully automated circular diamond sawblades......

Berlin Heidelberg 2011 Abstract: To research the loading characteristic of rocks with different structures cut by helical cutting mechanism (HCM), three different structures of rock (hard-soft-hard......
of Science and Technology Beijing, Beijing 100083, China摘 要:Bioleaching processes cause dramatic changes in the mechanical and chemical properties of waste rocks, and play an important role in metal recovery and dump stability. This study focused on the characteristics of waste rocks subjected to bioleaching. A series of experiments were conducted to investigate......
Determination of relationships between thermal conductivity and material properties of rocksKazim Grgülü摘 要:<正> Energy transfer between the adjacent parts of rocks in underground mines is widely influenced by the thermal conductivity of rocks. The relationships between the thermal conductivity and some material properties of rocks......
J. Cent. South Univ. (2020) 27: 2985-2998 DOI: https://doi.org/10.1007/s11771-020-4523-7 Experimental investigations on mechanical performance of rocks under fatigue loads and biaxial confinements... and sandstone under biaxial confinements. Experimental results demonstrate that the biaxial compressive strength of rocks under biaxial compression increases firstly, and subsequently decreases......
