通过收集整理金川矿区地应力实测数据,利用MATLAB软件中的相关工具,建立了主应力大小与埋深之间的回归函数关系,以及水平主应力和垂直主应力与埋深之间的回归函数关系,绘制了关系曲线;并研究归纳了金川矿区地应力场的分布规律。研究结果可为金川矿区安全高效生产提供指导。
Based on geo-stress data collected from in-situ measurement in Jinchuan mining district ,MATLAB soft-ware is used to establish a regression function relation between primary stress and buried depths ,and between horizon-tal primary stress and vertical primary stress and buried depths , according to which relation curves are drawn .Geo-stress distribution patterns are analyzed and summarized .The results can be helpful for safe and efficient operation in Jinchuan mining district .
