层状岩体是露天与地下开采矿山中常见的岩体类型之一，运用相似模拟的试验方法，以云南某矿山为原型进行了地下开采的模拟研究。在遵循相似理论的前提下，根据现场工程地质情况，选择了合适的剖面作为研究对象，确定模型的参数、相似材料的配比，然后进行试验。试验研究结果表明，顶板围岩变形从外到内表现为：外部沿层面滑动，中部沿层面向下移动，内部向采空区弯曲；从上到下表现为：上部沿层面滑动，中部沿层面向采空区弯曲，下部竖直向下滑动。试验结果可为以后类似条件矿山开采提供参考。

Layered rock mass is one of the common types of rock mass in open-pit and underground mining ,this paper used the method of analog simulation experiment onone mine in Yunnan as a prototype for underground mining simulation study .Under the premise of the similarity theory ,the paper chosean appropriate section as the research ob-ject according to the engineering geological conditions of the scene .So the model parameters and ratio of similar mate-rials can be decided to do the experiment .Deformation laws of surrounding rock are obtained ,outside-to-inside:it slips along the bedding in the external of the bedding ,slips down along the bedding in the middle of the bedding ,bends to the gob in the inner of the bedding;top-to-bottom:it slips along the bedding in the top of the bedding ,bends to the gob in the middle of the bedding ,slides down vertically in the bottom of the bedding .The results provide a certain ba-sis for further exploitation of such mines .
