| 摘 要： | 某高岭土矿区主要由下白垩统粉砂岩、泥岩、页岩和燕山期石英斑岩（霏细斑岩）构成，基岩节理、裂隙较发育，发育有J1、J2两组节理。据开发利用方案，开采过程及开采结束时，矿区开采边坡最终境界形成PNE、PSE及PSW3个边坡。借助赤平投影图，直观地分析结构面组合与边坡坡面的空间关系，运用二分法和三分法确定该矿区最终境界3个边坡整体处于稳定状态。

| Abstract: | The strata in a kaolin mine area are mainly lower Cretaceous siltstone, mudstone, shale and Yanshanian quartz porphyry （felsophyre）, rather developed bedrock joints and fissures, including J1 and J2 two sets of joint. According to exploitation and utilization scheme, during the mining process to the mining ending, eventually have formed PNE, PSE and Psw three bordering slopes. In virtue of stereogram can intuitively analyze spatial relationship between textural plane association and slope surface, using dichotomy and trichotomy methods to validate the final three bordering slopes are in stable state. |
