... on mineral composition of the rock and thermal conductivities of the minerals, as well as porosity and thermal conductivity of the pore water. Therefore, a quantitative relation between thermal conductivities of a given rock type with certain lithology and its porosity might be useful to approximately...

... investigates the impact of substrate crystal structure on the bonding strength of the rock-shotcrete interface. Gabbros and basalts used in this study have similar mineral compositions but have different grain sizes due to different cooling rates. Applying plain shotcrete to substrate samples to study...

... and economic further drilling in Southwestern Tarim of China. During the process of qualitative analysis for wellbore collapse, mineral composition, hydration ability and microstructure characteristics are indicators of the reason for wellbore collapse (e.g. DeNinno et al. 2016, Mohammed et al. 2019...
