The Laser microprobe analysis shows that the argon isotope is evenly distributed in the muscovite. The preliminary conclusion is (1) muscovite in high-pressure metamorphic orthogneiss does not contain excess argon and can be the object for 40Ar/39Ar dating;(2) muscovite in the Qinglongshan eclogite contains large amounts of excess ...

由此得出的初步结论是：①高压变质的正片麻岩中的白云母中不含过剩Ar，这类矿物可以作为~(40)Ar/~(39)Ar同位素测年的对象；②青龙山榴辉岩中的白云母含大量过剩氩，而作为其围岩的超高压正片麻岩中的白云母却不含过剩氩，这一事实证明了榴辉岩中白云母的过剩氩不是来自围岩，而是榴辉岩自身继承的。

In the light of all kinds of structural faces and their assembles along tunnel, the place and growth depth of instable cuneiform body in tunnel wall rock could be predicted, then its volume and weight of instable cuneiform body are estimated based on the equator plane projecting method and the solid body ratio geometry method, which offers reliable geologic data for designing corresponding supporting measure.

摘要利用赤平投影法和实体比例几何法分析隧洞围岩稳定性，根据隧洞沿线所遇结构面相互组合形式，预测隧洞围岩不稳定楔形体的位置及其发育深度，从而估算不稳定楔形岩块的体积和重量，为设计相应的支护措施提供可靠的地质依据。

At first the index system was built on the basis of survey; then 500 data was gained from the more than 800 examples of 72 tunnels; thus the quantitative evaluation was achieved. Finally, through case studies, the judge method based on quantification theory was tested and a high precision and reliability is achieved.

通过对国内外情况的调查统计，得到了公路隧道围岩亚级分级的指标体系；并依托工程实际情况，在72条隧道中采集了800余条样本，从中选出了500条数据进行分析，完成了以数量化理论为基础的施工阶段围岩亚级的定量判定方法研究，并通过工程实例对判定方法进行了检验。

We draw a conclusion,which is controlled wall-rock s durative distortion and scraggy in deepness-well by anchor-net and anchor-cable s shoring spout slurry secondary-shoring technology .

针对四矿矿井深部高地应力巷道支护现状及围岩特点，总结深井高地应力巷道支护原则，提出采用锚网喷—锚索喷注浆二次支护技术控制深井巷道围岩的持续变形和底鼓，并在工程实际中进行了支护实践。

According to the research on the displacement in Y direction, shear stress, plastic zone and vector of displacement of tunnel without lining after excavation of the tunnel, the characteristics and failure mechanism of tunnel are summarized in the state of the interface with one side is strong and the other is weak.

通过对开挖后的无衬砌隧道进行竖向位移、剪切应力、塑性区及围岩达到屈服状态时的位移矢量分析研究，总结出结构面两侧岩体上强下弱或下弱上强的状况下，围岩的力学特性和破坏模式；对隧道的选址、支护结构的设计和施工具有广泛的借鉴意义与指导作用。

By the study, after the tunnel is timbered as the original designation, the plastic scope of the surrounding rock's distortion is controlled obviously, and the stability of surrounding rock is strengthened.

通过研究认为，隧道按原设计方案支护后，围岩的变形及塑性区范围得到明显控制，增强了长子面围岩的稳定性。

Take different timbering kind to the different country rock of iron ore of boreal 洺 river and place, assure the stability of country rock effectively.

对北洺河铁矿的不同围岩和部位采取不同的支护方式，有效地保证围岩的稳定性。

Whether we can caculate andimitate the fluid change character of surrounding rock or not,whichhas more important meaning in selecting the project of timbering andcontrol.

能否准确地计算和模拟围岩的流变行为，对于我们选择支护和围岩控制方案，具有极其重要的意义。

The paper researched the stress fields and the deformation and breakage characters of wall rock of laneway along the gob about the fully mechanized in deep mine, which establish the theory basis of the wall rock transmogrification of the laneway along the gob.

本文研究了深井综放开采沿空掘巷的围岩的应力场及破坏特征，为探讨沿空掘巷围岩变形奠定了一定的理论基础。

On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

本文在大量测试工作基础上，利用煤岩学与有机地球化学资料，分析了煤系油气的来源，认为本区延安组煤系煤层生油潜力差，煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生，油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系；通过对煤层及围岩一系列物性参数的测试，分析与评价了煤岩层的生、储、盖、渗性能与可抽放性，得出主采4_(-2)号煤层属中等储集、低渗透层，围岩封闭性差，渗透性高，煤层瓦斯含量低，而顶板砂岩瓦斯含量高，为采面瓦斯涌出的主要来源。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
