摘要： This paper attempts to disclose the mechanical behavior and deformation performance of the resin anchor of the roadway in high temperature, deep mines, under the coupling between stress and temperature. Drawing on the relevant theories on thermomechanical coupling, this paper tests the strength, elastic modulus, Poisson's ratio and rheological performance of the anchoring resin under thermomechanical coupling, and compares the pull-out and rheological performances of the resin anchored layer under different temperatures and stresses. The results show that: With the increase in test temperature, the anchoring resin witnessed a gradual decline in its compressive strength and yield stress, a continuous decrease of its elastic modulus, a gradual growth in the Poisson's ratio, and a reduction in the yield point; The rheological deformation of the anchoring resin is affected by test temperature and stress; There is a negative correlation between the ambient temperature and the pull-out force needed to displace the anchoring resin by a certain distance, under the high temperature environment; In high-temperature, deep mines, anchoring resin is significantly affected by the ambient temperature and stress. The research findings lay the theoretical basis for the advancement of roadway support technique in deep mines under thermomechanical coupling.
