| Abstract: | Based on the geological conditions of Ronghua mine, analyses the failure mechanism of soft rock tunnel surrounding rock, puts for- ward the combined retaining technology solutions of ＂pre-stressed full anchor support ＋ inverted arch ＋ grouting reinforcement＂. Using FLAC3D software for the support scheme similar simulation research, the simulation results show that, the combined support scheme can effectively control the deformation and failure of the roadway surrounding rock, improve the capacity for safe production in coal mine, and has great application value. |
