| 中文摘要 | 采用应力解除法,在丰山铜矿-50 m和-100 m中段进行了6个点的三维应力测试,获得了6个测点的三维地应力资料。结果表明:矿体南缘应力值较大,最大主应力在15 MPa左右,北缘应力值较小,最大主应力在8.0 MPa左右;矿区地应力随地形起伏而变化,明显受地形地貌控制,同时岩体自重和构造作用是形成地应力的主要因素,二者在不同区域所产生的影响也不同,在南区以构造应力为主,深部地区以自重为主。为该矿的生产和巷道支护设计提供了可靠依据。; A three-dimensional stress testing was conduced at 6 points at-50 m and-100 m levels of Fengshan copper deposit by stress relief method,obtaining the 3D geo-stress data of the 6 measuring points.The results indicate that the geo-stress in the south is larger,with the biggest principal stress being about 15 MPa;and that in the north is smaller,with the biggest principal stress being about 8.0 MPa.The geo-stress in the mining area changes along with the topographic relief,and is obviously controlled by topography and geomorphology.The deadweight of the rock-mass and the tectonism are the main factors forming the geo-stress,and they have different effects on the different areas,with the south area mainly affected by tectonic stress,and the deep area mainly by deadweight.The results provide a reliable basis for the production and tunnel support design of Fengshan Copper Mine.; 国家自然科学基金项目(编号:50274043); 湖南省安全科技项目(编号:07-19); 中国博士后科学基金项目(编号:20090450421) |
