矿山开采中断层等弱面的存在,不仅改变了地表移动变形范围,同时由于断层露头地表的变形集中而形成塌陷台阶,增大了地表采动损害程度.根据断层面倾角与基岩移动角之间的关系,分析了断层对地表移动范围和非连续变形的影响规律,探讨了断层露头处台阶和裂缝的计算方法,实例分析表明,计算的断层台阶尺寸与实际观测相符,可以为有断层的地面建筑物布置和地下开采优化提供一定的技术依据.
The existence of weak surface such as faults in mine exploitation not only changes the range of surface deformation but also forms the collapse step due to the concentrated deformation of the outcrop of the fault outcrop and increases the degree of surface mining damage.According to the angle of fault plane and the bedrock movement angle The relationship between the fault and the surface movement range and discontinuity deformation is analyzed. The calculation method of the step and the crack at the outcrop of the fault is discussed. The case study shows that the calculated step size of the fault coincides with the actual observation, Ground building layout and optimization of underground mining provide some technical basis.
