材料力学课程是采矿工程专业非常重要的专业基础课。收集、整理并讲授与专业相关的教学案例,可以有效提高本专业材料力学课程的教学效果。在科学技术的推动下,我国的采矿工程行业取得了蓬勃发展,获得了众多优秀成果,也带来了一些失败教训。如果作为教学案例展示给采矿工程专业的大学生,将会使得课堂教学更加充满活力。本文依据材料力学的章节安排,分别列举了与采矿工程专业有关的一些对应案例,包括:非全长粘结锚杆的轴向拉伸、矿柱的轴向压缩、锚杆托盘的剪切和挤压、巷道穿越断层时的剪切、矿用钻机钻杆的扭转、顶板的固支梁和悬臂梁假说、单轴和三轴压缩条件下岩石的强度理论、掘进机传动轴的组合变形、单体支柱的压杆失稳以及竖井罐笼的坠落事故等。这些案例分别对应于材料力学课程中的各个章节,可为授课教师课堂教学提供参考。

[Abstract]
Material mechanics is a very important professional basic course for mining engineering. Collecting, collating and teaching the related cases of mining engineering can effectively improve the teaching effect. Driven by science and technology, mining engineering in China has achieved vigorous development, including many construction achievements and also many failure cases. If these cases are selected as teaching cases, they can make the course full of vitality. Based on the curriculum of material mechanics, several representative cases related to mining engineering are listed in this paper, including the axial tensioning of non-full-length anchors, axial compression of the mining pillar, shearing and extrusion of anchor trays, shearing of the horizontal roadway crossing normal fault, twist of the drill pipe of mining rigs, hypotheses of the fixed beam and cantilever beam for the roof, strength theory of rocks under uniaxial or triaxial compression, the combined deformation of the transmission shaft of the roadheader, the instability of the compressive single hydraulic prop, and the fall accidents of the shaft cage. The above cases refer to every chapters in the course of Material Mechanics, and they can provide reference for the classroom teaching of the instructors.
