基于GPS和回归分析的露天铁矿边坡稳定评价

Evaluation of the Steep Slope Stability in Surface Mine Based on Theory of GPS And Regression Analysis

随着露天开采的延伸,高陡边坡给矿山带来严重威胁,结合河北某铁矿边坡变形GPS监测及对监测数据进行回归分析处理,建立露天转地下开采矿山的边坡动态监控系统及边坡稳定的评价方法,初步掌握不稳定边帮的移动规律。从而解决在露天转地下开采过渡中出现的高边坡稳定性问题,并为解决相关的方法设计、参数设置、技术措施以及后期边坡控制治理提供可靠的依据,确保矿山从露天开采向地下开采顺利过渡,保持矿山的稳定而长期发展。

With the opencast working,Surface Mine is full of danger because of rock slope. In this paper,the monitoring system configuration and data processing are discussed in combination with GPS monitoring of slope deformation in an Iron Mine. In order to seize the rule of rock Stability and provid a more reliable basis for taking measures for control the rock stability,the dynamic monitoring system and rock Stability evaluation method are developed. The rock Stability in the surface mine is resolved so as to control the steep slope, which can hepe to the development of the Surface Mine.
