开采

Coal mining exists badly negative exteriority,it has restricted seriously the sustainable development of coal and diggings.

矿产资源开采存在着严重的负外部性，很大程度地影响到矿产资源及矿区的可持续利用和发展。

The three-dimensional terrain model is made for reproducing diggings sight.

矿区三维地质模型的研建，主要采用矿山开采过程中产生的数据，建立矿区的三维地形模型，三维地下地质体模型，三维边坡形态模型。

Exploitation to the point of diminishing returns.

开采超过一定的程度使收益递减。

Chrome diopside is mined in a remote location in Eastern Siberia known as Inagli in the state of Sakha.

铬透辉是在偏僻的地方开采西伯利亚东部称为inagli在萨哈州。

With development of economy in our country, demand for resources in especial for altogether coal have increasingly augmented according to the booming market. Though mechanization in the coal industry had been surprisingly progressed by the least 50 years, the technology of blasting engineering has been importantly seized on exploiting coal yet, especially, aiming at statue quo of disbalance development in technology and science.

随着我国经济的快速发展，市场对能源的需求尤其是对煤炭的需求大幅度提高，虽然煤炭生产综合机械化水平不断的提高，但是采用爆破技术采煤仍然占有一席之地，尤其针对我国目前技术水平发展不平衡的现状，对于赋存大量倾斜煤层和复杂煤层环境条件，开展爆破开采技术优化的研究是必要的也是急需的。

While the rest of the pack gleefully mined rock's past for their look and attitude, Dengler strode the stage like a poker-faced colossus: living proof that The Boys from the Brazil really did exist (Dengler is, disconcertingly, of German and Colombian descent).

而其余的包兴高采烈地开采石头'的过去对他们的期待和态度，丹格勒大步舞台像一个面无表情的巨人：居住证明，从巴西的男孩确实存在（丹格勒是令人不安的是，德国和哥伦比亚血统）。

As the easily discoverable energy has been exploited,the prospecting will become more and more difficult, and we need to advance theprospecting technology urgently.

鉴于容易找到的资源已经被发现和开采，随着时间的推移勘探任务的难度将日益增加，亟待于提高勘探技术。

The height of coal seam, the dispensability and compressibility of broken roof gangue, and the size of the broken block of PKS are the main evaluating factors of water-flowing fracture, which are concerned with the critical distance between PKS location and mining seam.

对导水裂隙带高度产生影响的主关键层与开采煤层临界距离主要与煤层采高、顶板碎胀压实特性、主关键层破断块度等因素有关，可以粗略按7~10倍煤层采高计算该临界距离。

In distillation,it is volatility; in absorption ,it is solubility; in extraction,it is distribution coefficient.

在吸收，脂肪；在开采，分配系数。

This paper introduced the use of differential pressure meters which use a double cone as the primary differential pressure producer. Its typical structure helps the V-cone flow meter have strong ability of flow adjustment, and operate with good accuracy at low DP's.

差压式V锥流量计独特的结构使其具有较强的流动调整能力，可测湿气体，能在低差压下测量煤层气等显著优点，已在美国的煤层气工业开采中得到了大量的应用。

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。
