摘　　要：硬厚岩浆岩在我国多个矿区广泛分布,硬厚岩浆岩对上覆岩层结构、离层空间分布等都起着决定性的控制作用。文章利用数值模拟(UDEC2D)研究了工作面高位硬厚岩浆岩下采动地表沉陷规律。结果表明:在硬厚岩浆岩破断前,作为主关键层控制着地表下沉量,岩浆岩破断后导致地表下沉量出现跳跃式增加。Hard and thick magmatic rocks are widely distributed in many mining areas in China. Hard and thick magmatic rocks play a decisive role in controlling the overlying strata structure and the distribution of the abscission layer space. In this paper,numerical simulation（ UDEC2 D） was used to study the surface subsidence law of mining under high hard and thick igneous rocks. Research shows that before the hard thick magmatite break,as the main key stratum it control the surface subsidence,after the magmatite break,it cause surface subsidence leap increase.
