杭来湾矿近浅埋煤层开采覆岩移动规律研究

Study on Overburden Strata Movement Laws of Hanglaiwan Coal Mine Similar Shallow Seam Mining

通过相似物理模型实验对30101首采工作面开采时的覆岩移动规律进行研究,得出了杭来湾矿近浅埋工作面开采时的覆岩结构特征、关键层破断规律及关键层和地表移动规律,为具有相同地质条件煤层的安全开采及覆岩移动规律研究提供参考。

Uses large mining height fully-mechanized method,study on the rules of overlying strata movement of 30101 first mining face by physical modeling experiment,results obtained the overlying strata structure features,the broken law of key strata moving,the movement law of surface and key strata of similar shallow seam large mining height fully-mechanized face in Hanglaiwan,which provided references for safe mining and study on overburden strata movement laws of coal seam with similar geological condition.
