Using seasonal temperature difference in underground surrounding rocks to cooling ventilation airflow: A conceptual model and simulation study by Zhu, Shuai, Cheng, Jianwei, Song, Wanting, Borowski, Marek, Zhang, Yongjun, Yu, Baohai, Wang, Yue, Qi, Chang, Tukkaraja, Purushotham, Hua, Gang, Xu, Yonggang, Ghosh, Apurna, Wang, Chao, Peng, Yun

“…In order to reduce the heat hazard effectively, it is necessary to investigate the temperature distribution characteristics and regulation of the surrounding rock of the mine tunnels. Based on field measurement data from a Chinese coal mine, the present study probes into the dynamic law of periodic variation of the heat regulation circle (HRC) in surrounding rocks, which is featured by the serious heat hazard, and further reveals the evolution characteristics of the physical range of HRC and the temperature field distribution. …”

Iron mineralization at the Songhu deposit, Chinese Western Tianshan: a type locality with regional metallogenic implications by Wang, C., Wang, Y., Dong, L., Qin, K., Evans, Noreen, Zhang, B., Ren, Y.

“…Hosted by volcaniclastics of the Carboniferous Dahalajunshan Formation, the Songhu iron deposit is located in the central segment of the Awulale metallogenic belt, Chinese Western Tianshan. Mineralization and alteration are structurally controlled by orogen-parallel NWW-striking faults. …”

Provenance of Early Paleozoic metasediments in the central Chinese Altai: Implications for tectonic affinity of the Altai-Mongolia terrane in the Central Asian Orogenic Belt by Wang, Y., Long, X., Wilde, Simon, Xu, H., Sun, M., Xiao, W., Yuan, C., Cai, K.

“…This craton provided Precambrian materials for the Early Paleozoic metasedimentary rocks now exposed in the Chinese Altai, and therefore suggests that the whole Altai-Mongolia terrane has a close tectonic affinity to the Tarim Craton.…”

Mesozoic intraplate granitic magmatism in the Altai accretionary orogen, NW China: implications for the orogenic architecture and crustal growth by Wang, T., Jahn, B., Kovach, V.P., Tong, Y., Wilde, Simon, Hong, D., Li, S., Salnikova, E.B.

“…We also used whole-rock geochemical, Sr-Nd isotopic and zircon Hf isotopic data to constrain the generation for these granitic rocks and to evaluate the implications for vertical crustal growth in this region. …”

Practical application of failure criteria in determining safe mud weight windows in drilling operations by Gholami, Raoof, Moradzadeh, A., Rasouli, V., Hanachi, J.

“…It was concluded that the Mogi-Coulomb criterion is a better failure criterion as it considers the effect of the intermediate principal stress component in the failure analysis. © 2013 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences.…”

Experimental Investigation of the Threshold Pressure Gradient on Saturated/Unsaturated Flow in the Ultra-low Permeability Reservoirs by Xie, Sam, He, S., Jiao, C., Zhu, H., Fu, C., Lei, G.

“…The threshold pressure gradient in the saturated and unsaturated flows are analyzed with the investigation on the pressure variation from downstream and upstream of the rock cores. The experimental results indicate that the threshold pressure gradient doesn′t exist in the ultra-low permeability rocks with saturated flow of normal brine and kerosene. …”
