Research on Hard rock Tunnel Excavation Rapid Construction Key Technology and Its Construction Technology
Abstract：Donghuantuo Coal Mine's hard rock tunnel construction is slow, which seriously influences mine production. This pa- per conducts detailed and systematic experiments and researches on the physical properties of surrounding rock of Donghuantuo Coal Mine' s hard rock crosscut tunnel by means of theory research and experiment measuring. Based on NATM method, the technique and technology of rapid construction in hard rock crosscut tunnel is designed and presented, which improves the speed of tunnel excavation and has significance on deeper exploitation of coal mine.
