采动覆岩载荷的动态传递过程研究

Dynamic changes process study of movement of underground-induced strata

利用FLAC数值模拟软件建立矿区具体工作面开采模型,模拟研究了随着煤层的开采关键层上覆岩层载荷的动态传递过程,提出了次关键层对关键层所受载荷及破断起控制作用,并给出应用组合载荷的计算方法来计算或预测随着工作面的开挖关键层所受载荷的大小及其动态变化过程的方法。

Imitate the software establishment mineral area to concretely work with the FLAC number the noodles mine model, the dynamic state which imitates to study to mine a key layer top rock strata to carry a lotus along with the coal seam delivers process, putting forward a time a key layer to the key layer is carried a lotus and break to break a control function, and give an applied combination carry the calculation method of lotus to compute or predict along with work the noodles open to dig the method of the variety process of size and its dynamic state of carrying the lotus that key layer is subjected to.
