刘家梁矿皮运下山锚杆支护工艺的创新设计

The Innovative Design of Bolt Supporting Device of Pelts down in Liujialiang Mine

现有的锚杆支护设计方法很多,如基于以往经验和围岩分类的经验设计法,基于假说和解析计算的理论设计法,以及现场监测数据为基础的监控设计法。基于地址勘测和地址力学评估,为锚杆支护装置设计提供精确力学设计参数,采用极限平衡方法对锚索进行校核,提高了设计精度。

There are many existing design methods of bolt supporting, such as the experience design method based on the experience and surrounding rock classification, the theoretical design method based on hypothesis and analytical calculation, and the monitoring design method based on field monitoring data. Based on the site reconnaissance and site mechanics assessment, provided precise mechanical design parameters for the design of bolt supporting device, and used the limit equilibrium method to check the cable to improve the accuracy of the design.
