摘　　要：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 coal mine can＇t very good cohesion between tunneling and supporting, greatly affected the driving efficiency of machine problems, this paper proposes a rectangular tunnel temporary support equipment, combine the temporary support and permanent support, improve the machine tunneling efficiency. And stress analysis was carried out on the base of dangerous situations and topology optimization.

关 键 词：临时支护设备 底座 矩形巷道 拓扑优化
