根据我国煤炭资源勘探开发中存在的问题与现状，在深层煤矿床赋存规律、开采地质条件及综合探测研究方面，急待解决的关键科学问题是：a。

Against the particularity of problem of gas bursting of Ⅱ(sub script 1) coal seam in Ludian gliding structure in west Henan, through a large amount of work of field surveys and interior research, and viewed from the basic theories of structural petrology, discussed some characteristics of mining gas hazard such as image, mechanism and tectonic control process.

摘要针对豫西芦店滑动构造区二(下标1)煤层瓦斯突出问题的特殊性，通过大量野外地质调查和室内研究工作，从构造岩石学基本理论着手，讨论了构造区矿井瓦斯地质灾害的表象、机理和构造控制作用。

After years of looking for steady work in this moribund coal region, Mariola Pokropp found it in 2006 at Eickhoff, a 145-year-old manufacturer of mining equipment that has reinvented itself in green times, retooling its assembly lines to make 30-ton gearboxes for wind power generation.

在这个即将消亡的产煤区，玛丽奥拉。博库珀在艾克霍夫公司找到了工作。这个具有145年历史的炼煤厂，重新找到了发展绿色能源的机会--它为风能开发购置了30吨的齿轮系统。

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。
