Though the load analysis on the tunnel roof wall-rock in the fault footwall tunnel, this paper solves the problem of the tunnel support of tunneling through the great fault;
通过对断层下盘巷道顶板围岩的受力分析，解决了煤巷掘进过大断层的巷道支护问题；
They connect the hanging wall of one fault to the footwall of another fault, and have special deforming feature, beside them on the hanging wall there are transverse anticlines.
转换斜坡连接一条断层的上盘和另一断层的下盘，具有特殊的变形特征，在转换斜坡近旁的断层系上盘伴生横向背斜。
If the relative movement of hanging wall and footwall is parallel to the strike of fault plane it is a strike slip fault.
如果断层上盘和下盘的岩石相对位移运动是平行断层面走向的，这种断层称为走滑断层。
If a fault has a vertical fault plane. How do we determine its hanging wall and footwall?
若一断层的断层面是直立的，我们怎么去确定它的上盘和下盘呢？
Whether mining in hanging wall or footwall, the elastic energy and vertical stress in the fault area will increase with the increase of fault dip Angle.
无论上盘或下盘开采，断层区域弹性能及垂直应力都随着断层倾角的增加而增加。
Fault plane divides faulted rock into two blocks. The block above the fault plane is called hanging wall; the block below the fault plane is named footwall.
断层面将发生断层的岩石分隔成两个岩块，我们将位于断层面之上的岩块叫做上盘，而将位于断层面之下的岩块称为下盘。
But to the region of nappe structure, by the reason of rising reverse fault top wall, so we just can calculate the fault geometry under the footwall breakpoint.
而对于逆断层因其上盘的上升过程，使得推算的断层只能获取下盘断点以下的构造形态。
If the relative movement of hanging wall and footwall is parallel to the strike of fault plane, it is a strike slip fault.
如果断层走向与区域构造的总体走向相平行，就称之为纵向断层；
