| 摘 要： | 本文通过对小官庄铁矿软岩的物化试验，全面分析了软岩的微观特性，得出了该矿主要存在两大类软岩：一类是以富含蒙脱石为特征的具有中一强膨胀的软宕；另一类是富含绿泥石或不含粘土矿物的节理化软岩，不存在膨胀性。在上述分析的基础上，并对软宕的微观特性进行了详细的实验室研究，从而为该矿此类软岩的支护提供了依据。

| Abstract: | Based on the physical-chemical tests of the soft rocks of Xiaoguanzhuang lron Mine, its mi-crocharacteristics are fuIly analysed. The soft rocks are divided into two classes. The first class is the mid-dle-strong swelling rocks which are mainly composed of montmonllonites. The second is no-swelling rockswhich are mainly composed of green rocks or joint rocks- By the above analyses, the microcharacteristics ofthe soft rock have been researched. |
