摘要
急倾斜煤层开采时，地表特别是软弱面露头，常常出现台阶、裂缝等非连续变形现象，对建筑物构成极大的威胁，甚至造成建筑物的严重损坏。本文采用数值计算方法。
ln mining steeply-inclined coal seams,the ground and particularly the outcrop of weak planes often experience non-continuous deformation in form of terrace or cracks,posing severe threat to and even damage of buildings.A study and discussion are made in the paper of the pattern and mechanism of this kind of deformation by using numerical calculation method.
