在急倾斜煤层的开采过程中,往往要碰到断层构造切割煤层。在这种条件下,煤层的采出,就相当于给处于平衡状态的断层面上盘岩体侧向卸载,破坏了原来相对平衡状态,引起岩体沿断层面发生滑动。位于断层带上的各种结构会受到较严重的破坏,甚至会沟通含水层造成水害。因而研究掌握断层切割岩体的移动规律,对解决“三下”煤柱开采问题就尤为重要。
In the mining process of steep coal seam, it is often necessary to hit the fault structure to cut the coal seam. Under such conditions, the mining of the coal seam is equivalent to unloading lateral side of the rock mass on the fault surface in balance state, destroying the original relative equilibrium state and causing the rock mass to slide along the fault surface. Various structures on the fault belt can be severely damaged and can even cause water damage to aquifers. Therefore, studying the rule of the movement of fault-cut rock mass is particularly important for solving the “three underneath” coal pillar mining problems.
