Abstract
In this paper, the dynamic loading tests of sandstone after heat treatment at 25-800?C are carried out by using the split Hopkinson pressure bar test system. Combined with the theory of energy dissipation, the dynamic fracture and energy consumption characteristics of coal-series sandstone are systematically studied. The test results illustrate that the dynamic fracture and energy consumption characteristics of sandstone are mainly related to the changes of internal moisture and cementing materials.
