摘　　要：实践教学是采矿工程教学中的一个重要环节。针对采矿工程实践教学中面临的困境与不足,该文将光弹性法引入采矿工程实践教学过程中,介绍将二维动态相移数字光弹性法应用于复合顶板巷道围岩应力分布求解的教学案例,包括数字模型设计、透明实体模型的3D打印、相移光弹性实验和应力场的自动解算,得到复合顶板巷道模型的全场应力分布,丰富采矿工程实践教学的内容,有助于采矿工程学生实验能力的培养、对围岩变形破坏及围岩应力场动态演化过程的认识。Practical teaching is one of key course in the teaching of Mining Engineering.For the difficulties encountered in the teaching of mining engineering,this paper introduced the application of photoelasticity coupling with 3D printing technique in practical teaching process of mining engineering.A teaching case of applying 2D dynamic phase-shifting digital photoelasticity to solve the stress distribution of surrounding rock of composite roof roadway is introduced,including digital model design,3D printing of transparent solid model,phase-shifting photoelasticity experiment and automatic solution of stress field.The full-field stress distribution of composite roof roadway models is obtained,which enriches the content of practical teaching of mining engineering.It is helpful to cultivate the experimental ability of mining engineering students as well as to understand the deformation and failure of surrounding rock and the dynamic evolution process of surrounding rock stress field.
