开采

With little to no oversight, mining accidents are a frequent occurrence in this Andean country.

在较少或根本就没有勘查的情况下对矿藏进行开采，采矿事故就成为了该安迪斯山脉国家的家常便饭。

Many phenomenon due to deep dip angle coal seam mining are still explained very well. There are a lot of deep dip angle coal seam mining district in China, the problem of miming subsidence is very general, so the research is of theory mining and practical value.

实践中，我国很多矿区有大量的倾斜煤层存在，倾斜煤层开采沉陷与变形预计问题普遍存在，需要我们对这类矿山的地表移动规律问题进行全面研究，因而该项研究具有重要的理论意义和生产实用价值。

Because the increasing of dip angle can lead to special strata behavior which cause difficulties to mining, The strata behavior theory can not be simpely borrowed from that of flat and gently inclined seams. In order to cut down roof accidents and increase production efficiency, the strata movement and stress distribution must be reassessed for seam with deep dip angle.

煤层倾角增大带来了矿压显现的特殊性和开采上的困难，不能再简单地借用水平和缓倾斜煤层的矿压理论，而必须对大倾角煤层围岩运动与应力分布予以重新评价，以降低顶板事故，提高生产效率。

Contour mining is the main type of mining used in Appalachia. The miner exca

等高开采是阿巴拉契亚地区的主要采矿方式。

Mining Subsidence ; Soil water interactions ; Super static pore pressure ; Thick aqueous soil layer.

开采沉陷；水土相互作用；超静孔隙水压力；厚松散含水层

The work of this paper is very important to the theory and engineering application on coal mining above aquifer.

本文的工作对带压开采的安全具有较深的理论价值与应用价值。

The aquifer consolidation model under the condition of exploitation in water resources is established.

建立了该水源地开采条件下的含水层固结模型。

This paper discusses the application of horizontal directional drilling technology in shallow least permeable aquifer groundwater extraction.

对导向钻进铺管技术在浅层低渗透性含水层地下水开采中的工艺进行了详细探讨。

By using the comprehensive theory and method developed in the thesis, we can classify the size of rockburst possibility of a specific mine before mining, export the possible rockburst area in graph.

在此基础上，首次建立了硬岩矿床开采的岩爆倾向预测综合理论，并提出了具体的预测实施方法和程序。

When water content in the reservoir increases in the process of water flooding,argillaceous cement of sandstone will be hydrated.

在油田开采过程中，随着采出量的增大，油层的含油饱和度会降低，而含水饱和度将升高。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
