Abstract Based on an analysis of impact of temperature on rocks and internal stress distribution of rock under temperature field, the rock breaking effect of disc cutters under temperature-stress coupling effect was studied by designing a heating test device. The heating device design and impact of temperature field on rock are the key points of design. The impact of temperature on rock and internal stress distribution of rock under temperature field were simulated by ABAQUS software. The design of experimental device is of great significance in study of influence on rock mechanical behavior, improvement of rock breaking efficiency, enhancement of geological adaptability and prolonging service life of cutter.
