摘要
以袁店一矿103采区回风大巷为研究对象,采用FLAC3D模拟地质构造发育断层区内巷道围岩破坏特征,分析了"深-浅耦合控制"、"深-浅耦合+底断面控制"、"深-浅耦合+全断面控制"3种不同方案的控制特点。结果表明:采用"深-浅耦合+全断面控制",能够更加有效的控制地质构造发育断层区内巷道围岩的变形破坏,取得理想的效果;根据地质构造发育程度,合理选择"深-浅耦合+底断面控制"经济效果更为明显。
Taking return air roadway of Yuandian No. 1 Mine in 103 mining area as the research object, we simulated the failure charac- teristics of roadway surrounding rock of geological tectonic development fault zone by FLAC3D, also analyzed the control characteristics of three different schemes ： ＂ deep - shallow coupling control ＂ , ＂ deep - shallow coupling ＋ bottom section control ＂ ,＂ the whole section control ＋ deep - shallow coupling＂. Tile results show that ＂the whole section control ＋ deep - shallow coupling＂ can more ef- fectively control deformation and failure and achieve the ideal effect ; according to the development degree of the geological structure, a reasonable choice of ＂bottom section control ＋ deep - shallow coupling＂ will get more obviously economic effect.
