露天矿台阶爆破虚拟仿真系统的建设与实践

Construction and practice of virtual simulation experimental teaching system for bench blasting in open-pit mine

针对露天矿台阶爆破实验教学中存在的现场实习风险大、师资不足、模型教学失真等问题,福州大学采矿工程专业建立了露天矿台阶爆破虚拟仿真系统。该系统采用第一视角的主场景方式,对露天矿台阶爆破场景进行三维仿真,对爆破流程进行虚拟设计,实现线上线下全过程管理,并设计动态仿真、交互嵌入,为学生带来"身临其境"的体验。该系统拓展了实验教学内容、广度和深度,有效地提高了教学效率和教学效果,加深了学生对露天矿台阶爆破的认识,让学生快速掌握露天矿台阶爆破的教学内容,提高了学生的学习兴趣、创新能力和科研能力。

In view of the problems existing in the open-pit mine bench blasting experiment teaching, such as the high risk of field practice, the shortage of teachers and the teaching model distortion, a virtual simulation system for open-pit mine bench blasting has been established for the mining engineering specialty of Fuzhou University. This system uses the main scene mode of the first perspective to carry out 3D simulation of the bench blasting scene of the open-pit mine, virtually designs the blasting process, realizes the whole process management online and offline and designs dynamic simulation and interactive embedding, so as to bring students "immersive" experience. This system expands the content, breadth and depth of experimental teaching, improves teaching efficiency and teaching effect, deepens students’ understanding of bench blasting in open-pit mine, enables students to quickly master the teaching content of bench blasting in open-pit mine and improves their learning interest, innovation ability and scientific research ability.
