下盘开采对断层及上盘煤层影响数值模拟

Numerical Simulation of Footwall Mining Effects on Fault and Topwall Seam

以某矿1301工作面从F10大断层的下盘穿过断层为研究对象,建立FLAC数值模型,研究了垂直应力、塑性区大小、垂直位移分布等关键参数,为确定煤柱大小提供依据。

By researching on 1301 face crossing through fault from the large F10 fault footwall ,the paper set up FLAC numerical model and researched the key parameters of vertical stress ,plastic zone size and vertical dis‐placement distribution ,etc .,which provided basis for the determination of coal pillar size .
