针对目前煤矿井下掘进和支护之间不能很好的衔接,极大地影响了掘进机的掘进效率的问题提出一种矩形巷道临时支护设备,将临时支护方式与永久支护结合起来,提高掘进机掘进效率。并对危险状况下的底座进行受力分析与拓扑优化。
Aiming at the problem that the underground excavation and support can not be well connected and greatly affect the heading efficiency of roadheader, a kind of temporary support equipment for rectangular roadway is proposed, which combines the temporary support and permanent support to improve Roadheader driving efficiency. And the base under dangerous conditions for stress analysis and topology optimization.
