The wall rocks destroy and deformation of compound roof roadway mainly refers to the roof falling caused by the weak bedding plane of the compound roof.

复合顶板回采巷道的围岩变形破坏，主要是复合顶板的层理弱面引起的顶板冒落。

However, rockmass with intercalated bed is mechanically unique, so it is reasonable to modify Formula BQ in order to match its feature.

针对含软弱夹层岩体的力学特性，探讨了如何以BQ分类为基础，经过适当修正以建立合适的围岩质量评价体系。

These responses are tested in different extents using the brachiopod fossils Rhynchospirifer and Stringocephalus, as well as their surrounding rocks.

上述认识不同程度地在Rhynchospirifer属和Stringocephalus属为代表的腕足动物及其围岩的研究中得到验证。

This paper introduces a successful experiment in grounting blocking against water in coal bunker and surrounding rock grouting strengthening by Malisan and a suitable proportion of catalysts,which have got a good effect and ensured the regular production of coal mine.

通过调研及试验，针对矿井的实际情况利用马丽散配以一定比例的催化剂对矿井煤仓漏水现象进行了注浆堵水处理，对巷道围岩进行了注浆加固，取得了很好的效果，保证了矿井的正常生产。

With the wide application of computer, numerical analysis for the stability of underground cavern has played a more and more important role.

随着计算机的广泛使用，数值方法在解决地下洞室围岩稳定问题中越来越发挥着重要的作用。

In addition,compared with CR method,the method has many advantages,such as sensitivity to the difference in resistivity or chargeability between a geological target and its country rock,higher efficiency and lower product cost etc.

此外，该方法与复电阻率法相比，具有对目标地质体和围岩的电阻率和极化率差异反映灵敏、效率高、成本低等优点，所以它是一种值得推广的找油气的电法勘探方法。

By disposal of partial least-squares regression, the collinearity of roadway surrounding rock displacement influence factors is removed and the principal components having optimum explanation to dependent variables are extracted. It makes node numbers of neural network input layer cut down to three from seven, and has effect of simplifying structure and strengthen stability of neural network.

通过偏最小二乘回归对巷道围岩的位移影响因子的处理，消除了影响因子的线性相关性，并提取了对因变量解释性最强的成分，使BP网络的输入层节点数目由原来的7个减少到3个，起到了简化网络结构，增强网络稳定性的作用。

The key of longwall mining along strike safely and efficiently is efficacious controlling of surrounding rock, and the difficult points of surrounding rock controlling are dynamic stability of system "R-S-F" has be made clear by the facts from site test, experimental study and theoretical analysis, and three patterns may cause system "R-S-F" destabilization, such as dislocation, consequentiality and retrogradation among R, S and F in the process of longwall face advancing is put forward in the paper .

大倾角煤层走向长壁工作面开采方法与装备研究由于其矿压显现和围岩破断活动的复杂性而进展缓慢，较少见到国外主要产煤国家此方面的专门文献，我国目前的研究、试验与使用水平处于国际该领域的前沿。

As to the large and complex underground caves, the stability problem of wall rock during the process of underground cave's excavating is connected with the constructible cost and management benefit of the whole power station project.

大型复杂地下洞室在开挖过程中的围岩稳定问题关系到整个水电站工程的建设成本和运营效益，是一个值得深入研究的问题。

The angle of dip give more affection on space convergence, the steep dip layer are stable fast than the flat dip layer.

研究结果表明：①围岩的倾角对内空收敛影响大，急倾斜岩层收敛稳定快于缓倾斜岩层。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
