Abstract: In view of problems existing in the experimental teaching of the mine rock mechanics and engineering, based on the advantages of cutting-edge experimental technologies such as CT scanning and 3D printing technology, the instruction model integrating theory and practice is constructed and applied to the experimental teaching of mine rock mechanics and engineering. The teaching practice has shown that the instruction model can effectively promote the students’ enthusiasm for participating in experiment and studying the experimental principle, which improves students’ mastery level and comprehensive practical ability of rock mechanics experiment theory and method.
