    摘要:

    材料力学课程是采矿工程专业较重要的专业基础课。收集、整理并讲授与专业相关的教学案例,可以有效提高材料力学课程的教学效果。在科学技术的推动下,中国采矿工程行业蓬勃发展,获得较多优秀成果,同时也有失败的教训。如果将这些成果及教训作为教学案例展示给采矿工程专业大学生,将会使得课堂教学更生动。依据材料力学的章节安排,分别列举与采矿工程专业相关案例,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,分别对应于材料力学课程各个章节,为授课教师课堂教学提供案例参考。

    Abstract:

    Material mechanics is an important professional basic course for mining engineering. Collecting, collating and teaching 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 achievements and failure cases. If these cases are selected as teaching cases, they can make the course lively. Based on the curriculum of material mechanics, several representative cases related to mining engineering are listed, 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, 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. They correspond to each chapter in the course of material mechanics, and can provide case reference for the classroom teaching of instructors.
