摘要
应用大型有限元分析软件ANSYS对急斜煤层综放开采中应用广泛的轻型单摆杆支架进行了有限元分析,根据支架应力及变形分布情况,得出了一些有益的结论。对于急斜矿井综放设备对综放生产的适应性,完善和优化综放支架架型和配套设备,提高支架的可靠性等方面具有重要意义。
The paper has analyzed uses the light single wobbling pole caving supports in longwall top- coal caving mining by the large - scale finite dement software ANSYS. According to the stress of the support and distribution situation of variation in shape, the paper has drawn some beneficial conclusions. It is much meaning to improve and optimize the type of support and the suited equipments, and increases reliability of caving powered support.
