薄煤层上覆岩层移动破坏规律探讨

Study on Law of Movement and Failure of Overlying Strata in Thin Coal Seam

以薄煤层工作面为研究对象,对其上覆岩层移动规律的探讨采用深基点观测、钻孔窥视、相似模拟及数值模拟等研究方法,研究结果表明:上覆岩层部分区域发生整体沉降,但未出现明显的层间离层现象。

The working surface of thin coal seam as the research object,the research method of the overlying strata movement law is studied by using the method of deep basic point observation, drilling,similar simulation and numerical simulation. Researching results show that：the overburden area occurred in the settlement, but there was no obvious interlayer separation phenomenon.
