Abstract: To address the problems of high safety risks and poor learning experience involved with the high-pressure abrasive jet rock breaking experiment teaching, the teaching contents and objectives were reconstructed based on application requirements. A simulating twin model, data interaction components, and flow logic algorithm were developed using the visualization function and script driven technology of Unity3D. A virtual simulation experimental platform for high-pressure abrasive jet rock breaking was constructed. The system aims to build an abrasive jet rock breaking teaching and training model guided by the concept of safe development. Targeting teachers and student users, this system provides a visual interactive teaching mode. It is characterized by high fidelity, good interactivity, and safety and reliability, which can break down the temporal and spatial limitations in teaching, and transfer teaching scenes from physical space to information space. This system provides a flexible and safety mode for student learning, which is benefit for the cultivation of practical innovation ability.
