本钢南芬露天铁矿产生大规模边坡滑体,威胁了矿山采场生产人员和设备的安全,极大地影响厂矿山的正常生产,促成了本钢南芬露天铁矿新一轮的边坡稳定性研究,本文正是在这一背景下,对本钢南芬露天铁矿的地质概况、生产概况和边坡滑体产生的现状进行了浅要介绍,然后通过对局部边坡岩体的岩性、构造、岩层产状等的地质调查和岩移监测结果分析,得出影响露天矿边坡稳定,并产生边坡滑体的主要原因是:岩体的岩性及结构特征、爆破震动、雨水渗透和生产中的人为因素。最后提出露天矿边坡稳定研究和防治工作的几点建议:建立边坡稳定技术研究机构和专职边坡施工维护队伍、防水排水、加固整治、岩移监测和控制爆破。
The large-scale slope slide generated by the Benfang Nanfen open-pit iron mine threatened the safety of the production staff and equipment in the mine stope and greatly affected the normal production of the mines and mines, resulting in the new round of edge of the Benfang Nanfen open-pit iron mine In this context, this paper briefly introduced the geological survey, production situation and current situation of slope slip in Nanfen open-pit iron mine of Benxi Iron and Steel Co., Ltd. After that, Lithology, structure, rock formation and other geological survey and monitoring results of rock movement monitoring results show that the impact of open-pit slope stability and slope landslide are the main reasons are: lithology and structural characteristics of rock mass, blasting vibration , Infiltration of rainwater and human factors in production. Lastly, some suggestions are put forward for the research on slope stability and prevention and control of open pit mine: to establish a slope stability technology research institute and a full-time slope construction and maintenance team, waterproofing and drainage, consolidation and treatment, rock movement monitoring and control blasting.
