The Da＇anshan coal mine already entered the deep mining stage, Geologic structure is complex by the fold geologic structure primarily in the Minefield, the mining coal working surface and the tunnel impact geostatic pressure occurs frequently, but so far has not conducted the system research.

大安山煤矿现已进入深部开采阶段，井田内以褶曲为主的地质构造复杂，采煤工作面和巷道冲击地压发生频繁，但到目前为止还没有进行过系统研究。

The article mainly discusses tunneling when there is more gas in the coal layer,utilizing the hish layer cracks using the hole in the high layer,in this way of inhaling the next layer gas as tunneling,the problem of the gas consistency above the ordinary level in some workplace because of the gas gushing form the next layer is sloved.

主要阐述了在高瓦斯煤层掘送时，利用高孔裂隙，采用高抽放钻孔、边掘边抽的方法，解决邻近层瓦斯涌出造成工作面局部瓦斯超限的问题。

In accordance with the case of large mining depth in Xingdong coal mine, study on coal floor strata failure depth test of working face 2121 was carried out by water injection test. According to variation of unit injection quantity and distance between testing boreholes and working face advance, coal floor strata failure depth was determined by continual water injection and intermitted monitoring.

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。
