薄基岩浅埋煤层覆岩活动规律的数值模拟研究

Numerical Simulation on Overburden Strata Behavior of Shallow Seams with Thin Bedrock

为研究薄基岩浅埋煤层开采过程中工作面上覆岩层的变形破坏规律,利用RFPA软件对神东矿区某工作面煤层顶板破坏进行数值分析,显现了上覆岩层在工作面推进过程中的破坏过程,得出了薄基岩浅埋煤层上覆岩层在开采过程中的活动特点。

To study the deformation and failure of overburden strata during the mining in shallow seams with thin bedrock, the research uses RFPA to simulate the roof failure in Shendong mine. The results show the damage process during the working face heading on the upper overburden strata and the movement of the upper overburden.
