In order to effectively solve the difficulty of setting up real experiments in the “Blasting Safety” course,the construction and practical research of integrated experimental teaching system are carried out based on virtual simulation technology and related patented technology.Taking the “design and implementation for blasting safety during roadway excavation” in the blasting safety project as an example,a experimental teaching platform for blasting safety during roadway excavation based on virtual simulation is developed,which can realize the whole process of blasting plan design,blasting construction and blasting hazard monitoring.Meanwhile,a virtual simulation system for emergency rescue of blasting fume poisoning accident during roadway excavation has been developed,which can realize the animation demonstration of blasting fume poisoning accidents,and interactively complete the two practical operations of self-rescue and mutual rescue of workers and rescue of rescuers in a virtual environment.Then the simulation model of rock tunnel excavation and blasting and the simulated electric detonator for teaching have been developed,which can complete four practical operations of blast hole arrangement,detonator detection,detonation network connection and network continuity detection.Based on above work,the teaching content of fusion experiment is designed.The research and exploration online experiment has the characteristics of heuristic,inquiry,multi-way and multi scheme; The comprehensive design offline experiment has the characteristics of interaction,team and design.The comprehensive design offline experiment has the characteristics of interaction,team and design.Teaching practice shows that online virtual simulation experiment not only greatly enriches the form of experimental teaching and enhances the interest of experimental courses,but also breaks through the limitations of time and region for experimental courses,and students can complete experimental tasks through the network anytime and anywhere.The offline physical simulation experiment not only cultivates the teamwork spirit of the students,but also deepens the students' understanding and application of the theoretical knowledge learned in the classroom,and their hands-on operation ability can be simultaneously improved.Combining the experimental teaching system,a hybrid teaching mode of combining virtual and real and complementing each other is constructed,which provides ideas and references for solving the difficult problems of blasting experimental courses.
