中文摘要：
针对软弱夹层赋存规律以及地球物理特征,运用费歇尔判别分析方法结合测井数据对钻孔控制地层进行软弱层识别。将该方法运用于F露天煤矿,以密度、声波、中子、伽马测井数据作为基础样本建立判别函数,结果表明,采用该方法能够有效的对钻孔周围地层软弱层位的识别,为边坡安全性评价提供依据。
英文摘要：
According to the law of occurrence and geophysical characteristics of weak interlayer, using Fischer discriminant analysis method , the article recognizes drilling control strata combining with logging data. This method is applied for open-pit mine, using density, sonic, neutron, gamma logging data as a basis sample discriminant function. The results show that this method can effectively identify weak layer of surrounding formation, which provide evidence for safety evaluation of open-pit slope.
