本文论述了该矿松动区滑坡体的工程水文地质、构造特征及其发展过程与规模.根据对滑坡体稳定性程度的分析,进行了相应的全预应力锚杆加固、全钢轨组合桩抗滑、预应力锚杆与钢轨组合桩联合支档、全削坡处理等多方案的对比研究,从该矿特殊情况与工程费用的工程比较出发,采用了合理的治理措施,实施后可为矿山多采回境界线以外的有用矿石90万吨。
This paper discusses engineering hydrogeology, tectonic characteristics, development process and scale of landslide body in loosening area of the mine.According to the analysis of the stability of landslide body, the corresponding full prestressed anchor reinforcement, anti-slide , Prestressed anchor and rail combined pile joint support, the whole slope and other multi-program comparison, from the mine special circumstances and project cost comparison project, the use of a reasonable control measures, after the implementation of more for the mine Mining 90 million tons of useful ore outside the boundary line.
