In order to meet the growing demand for iron ore， it is necessary to increase the mining of iron ore. When excavating a mine ， effective measures must be taken to ensure safety ， and reliable support measures must be taken when the underground tunnel is being driven. Due to the complex environment of the underground tunnel ， different supporting technologies must be selected in accordance with different spaces and geological conditions， so that it can ensure the safety of the mine during the excavation process， and lay a solid foundation for increasing the output of iron ore in China. Based on this ， this article briefly analyzes the roof support technology for rapid tunneling in iron ore mining.
