受断层影响的地表移动计算

分析了存在断层岩体的移动规律的变化，提出了断层影响先产生断层面离层，再进一步扩展的移动过程。并以此为依据建立了受断层影响的地表移动计算模式。断层影响的基本规律是在断层带形成一离层空间，断层影响下的地表移动是开采空间影响与开采在断层带上产生离层空间影响的叠加。影响断层出现台阶的大小与断层相对位置、断层倾角等诸因素相关。

CALCULATION OF SURFACE MOVEMENT INCURRED BY FAULT

Based on analysis of the change of rock movement induced by a fault, the influence of fault on rock movement is first represented by separation of fault plane and further propagation. And based on which a model is established for calculation of surface movement incurred by a fault. The basic rule of surface subsidence is that a separation space is formed in the faulted zone. And surface movement induced by a fault is a superposition of surface movement induced by space formed by coal mining, and that induced by a space formed by separation. It is also related to many factors, as the size of terrace,relative position and inclination of fault, etc.
