开采

They migrate past a gantlet of Japanese fishing nets that accidentally kill a few each year. They also feed off Russia's coast where oil firms seek new resources; threats include possible oil spills and collisions with ships.

每年灰鲸在迁徙的路上总有几头会意外被日本捕鱼船捕杀，在俄罗斯海域，石油开采也影响着灰鲸的迁徙，这些危险包括石油泄露或是与开采船支相撞。

When production can be greater than production, give rise to a series of hydro-geological environment.

当开采量大于可开采量时，会引起一系列的水文地质环境问题。

On the basis of the analytical result, the paper summarized the rule ofsupperterrane and ground's movement because of underground mining. At the sametime, the paper drew the curve of dynamic movement at the different mining stages.

根据应力和位移的分析结果，总结出了地下开采引起的上覆岩层和地表的移动规律，给出了不同开采阶段的地表动态移动曲线。

It is a new topic that rule of ground movement in steep coal seam mining, the overlying rock of steep coal seam mining have different homogeneousness in horizontal orientation. Its complexity make the research of this kind of problem process is very inadequate.

急倾斜煤层开采地表沉陷移动规律是地表沉陷研究领域中的一个新课题，急倾斜煤层由于开采上覆岩体在水平向的均质性不同，其复杂性更使这类问题的研究极不充分。

In the previous research, because mining subsidence"s inoculation and developing process is so complex that can"t touch, people give more attention on final result of rock damage; the overlying rock of steep coal seam mining have different homogeneousness in horizontal orientation. It"s complexity make the research of this kind of problem"s time process is very inadequate.

在以往的研究中，因开采沉陷的孕育和发展过程复杂而无法触及，人们将更多的注意力放在岩体破坏的最终结果；而急倾斜煤层开采上覆岩体在水平向的均质性不同，其复杂性更使这类时间过程的研究极不充分。

Refers to the material production sector which is engaged in extraction of natural resources and processing and reprocessing of minerals and agricultural products, including (1) extraction of natural resources, such as mining, salt production, logging (but not including hunting and fishing);(2) processing and reprocessing of farm and sideline produces, such as rice husking, flour milling, wine making, oil pressing, cotton ginning, silk reeling, spinning and weaving, and leather making;(3) manufacture of industrial products, such as steel making, iron smelting, chemicals manufacturing, petroleum processing, machine building, timber processing; water and gas production and electricity generation and supply;(4) repairing of industrial products such as the repairing of machnery and means of transport.

指从事自然资源的开采，对采掘品和农产品进行加工和再加工的物质生产部门。具体包括：（1）对自然资源的开采，如采矿晒盐森林采伐（但不包括禽兽捕猎和水产捕捞）；（2）对农副产品的加工再加工，如粮油加工食品加工轧花缫丝纺织制革等；（3）对采掘品的加工再加工，如炼铁炼钢化工生产机器制造木材加工等，以及电力自来水煤气的生产和供应等；（4）对工业品的修理翻新，如机器设备的修理交通运输工具的修理等。1984年以前农村的村及村以下办工业归属农业，1984年以后划归工业。

A theoretical model for predicting ground displacement and deformation due to mining of phosphate body in Wenjiaping by using hyperbolic tangent function was given in this paper.

针对文家坪磷矿地下开采岩体移动变形问题，给出了用于预测分析地下开采引起地表移动变形的双曲正切函数模型。

Thoughting of to°from the carbon esmissions the coal mine, China of the coal store quantity 600,000,000,000 tons, world three, can China mineral difficult death toll world a, incompletely statistics, 2004 death 6027 people, 2005 death 5986 people, 2006 death 5770 people, 07 and 08 also have no to die down it power, abroad relevant the expert appeal:China taken blood the coal have to be stop immoderation of mine.

由碳排放量想到煤炭开采，中国的煤炭储藏量6000亿吨，具世界第三，可中国矿难死亡人数全球第一，具不完全统计，2004年死亡6027人，2005年死亡5986人，2006年死亡5770人，07、08也毫无减弱之势，国外有关专家呼吁：带血的中国煤炭必须停止无节制的开采了。

The strata are Triassic Xujiahe group sand-shale stratum which containing coal layer. It is nearly three-century history about the coal layer exploitation. In that time, because of the outdated technique and inorganization, the coal caves have the characteristic of randomicity, concealment, universality, no obviously regularity and the small scale for single cave.

坝区地层为三叠系须家河组砂页岩含煤地层，煤层的开采已近300年历史，由于当时开采技术落后、无组织性，导致煤洞具有随机性、隐蔽性、广泛性、单洞规模小、无明显规律等特点。

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。
