工程爆破虚拟仿真实验教学资源建设

Construction of Teaching Resources for Blasting Engineering Virtual Simulation Experiment

高校开展工程爆破实验教学本身存在局限性,爆破危险品难以申购、实验环境安全标准严苛、实验操作危险性高且可重复性低等问题无法妥善解决。该文以中国矿业大学(北京)工程爆破实验课程为例,论述了建设虚拟仿真实验资源的必要性,介绍了工程爆破虚拟仿真实验教学平台以及实验资源建设的设计思路与过程。为最大程度还原真实场景,研发团队多次前往炸药工厂实地拍摄取材,结合理论课程内容,正确引导学生开展炸药爆速测试、猛度测试、起爆网络连接设计以及炮孔布设方案等实验内容,努力探索线上线下教学相结合的个性化、智能化实验教学新模式。

There are limitations in carrying out engineering blasting experiment teaching in universities.The problems of difficult purchase of blasting dangerous goods,strict safety standards for experimental environment,high risk and low repeatability of experimental operation cannot be properly solved.Taking the engineering blasting experiment course of China University of Mining and Technology(Beijing)as an example,this paper discussed the necessity of building virtual simulation experiment teaching resources,and introduced the engineering blasting virtual simulation experiment teaching platform,as well as the designed the idea and process of experimental resource construction.Relying on the theoretical course content,this resource can correctly guide students to carry out the following experimental content,such as explosive explosion speed test,intensity test,detonation network connection design and gun hole layout scheme design.In order to restore the real scene to the greatest extent,the R&D team went to the explosive factory to take on-site photos and materials for many times.Moreover,the team is taking the opportunity to explore a new personalized and intelligent experimental teaching mode combining online and offline teaching.
