摘要
基于荣华煤矿的地质条件,分析了软岩巷道围岩破坏机理,提出了"预应力全锚索加固+反底拱+注浆加固"联合支护技术方案,并采用FLAC3D软件对该支护方案进行相似模拟研究,结果表明,该联合支护方案有效地控制了巷道围岩破坏变形,提高了矿井的安全生产能力,具有较大的应用价值。
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.
