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.
