The paper selected 10 sample faces which have different features and havebeen finished minning, then evaluate the risk in the faces with the evaluateprogram write with Matlab to test the model.

论文选取10个具有不同特点的已完成开采的采煤工作面，采用Matlab编写了评价程序进行了评价试算。

Both of conventional continuous medium mechanics and noncontiguous medium mechanics, having strong pertinence, can abstract and simplify the rock model in research procedure, in which the rock body lying over the coal face can be considered as a static beam or board to leave out the push changes and the changes of property and load during the stability of overlying rock deformation has lost. Hence the derived profile equation is only the approximate expression of final subsidence of surface after the mining finished, and it is difficult to obtain the dynamic subsidence process of rock body.

传统的连续介质力学和非连续介质力学均具有针对性，在研究过程中将岩体模型抽象简化，将工作面上方的岩体看成是一静止的梁、板，省略了工作面的推进变化及覆岩在变形失稳时的性质和载荷的变化，得出的剖面方程仅是开采结束后地表的最终沉陷近似表达式，难以得到岩体的动态沉陷的过程。
