Investigating the Effect of Temperature Changes on the Physical Field of Surrounding Rock in a Deep Gold Mine by Xinghui Wu, Qifeng Guo, Peng Li, Fenhua Ren, Jie Zhang, Meifeng Cai

“…The numerical simulation results show that increasing the convective heat transfer coefficient not only increases the tensile stress of the heat transfer boundary but also increases the possibility of cracks, which makes the rock easier to crack. Based on the research results, we introduced the thermal-mechanical coupling disturbance range coefficient β = L/2D (β = 6–8) and proposed that the convective heat transfer coefficient is the reference index of the deep mining support structure, which can provide a theoretical basis and technical support for the selection of support materials.…”
