Blasting Engineering is a core course in urban underground engineering and mining engineering in universities, and teaching blasting experiments is an indispensable link in practical teaching. As explosive engineering has a characteristic of great danger, the traditional explosive engineering experiment construction is rugged enough to be carried out indoors, which inconveniences teaching. Therefore, more and more schools rely on virtual simulation platforms. According to the teaching idea and demand of explosive engineering virtual simulation, this paper builds a virtual simulation teaching platform for blasting experiment teaching. Unity3D, a development tool for virtual simulation systems, was utilized to ensure high compatibility when running on different platforms. Meanwhile, the 3DS Max and Maya were applied to build and improve a realistic model. Furthermore, problems like slow loading speed and non-realistic animation through the cloud rendering technology were solved. The software ANSYS was used to simulate the propagation mechanism of blasting vibration waves in different rock layers better to reflect the blasting vibration waves in practical engineering. Finally, the wave field cloud map was saved as a snapshot in the virtual simulation system, and virtual simulation experiments of blasting vibration were carried out. The practice and application results show that the virtual simulation experiment platform can enable students to participate in the experiments of explosive engineering independently and deeply and improve students' experimental experience and practical innovation ability.
