开采

Gilly Llewellyn, from the conservational organization WWF, says pollution and oiling gastroling oil and gas drilling are among many threats that could damage the Coral Sea's equal echo system.

自然资源保护组织WWF的Gilly Llewellyn认为污染及石油、天然气的开采都是可能破坏珊瑚海生态系统的威胁。

A fluid-solid coupling simulation must be made when people do an experimental research on similar materials in a mining area coved with water, but it has been not succeeded because people have not found the long-term suitable coupling materials.

水下煤矿开采在进行相似材料实验研究时都应进行固液两相模拟，但由于对两相实验材料的研究一直未取得突破性进展而未成功。

Because they have not been able to effectively degasify their mines, four of the attending Chinese coal mining companies immediately approached Tunaye Sai and Mitchell about using this state-of-the-art drilling technology.

因为他们未能有效degasify地雷四诊中，立即上前tunaye西煤炭开采公司和米切尔利用这个美国最先进钻井技术。

If we adopt normal methods to exploit,we can not have any economic benefit,but if we adopt double step horizontal wells,it can increase drainable area greatly,enhance individual well producing rate, achieve the Tarim Oil field's exploiting rule of\"wide spacing,high production\".

若采用常规方式开采，毫无经济效益，而利用双台水平井可大大增加泄油面积，可提高单井产量，实现&稀井高产&的开发效果。

With the increase of mining depth, the condition of roadway surrounding rock constantly changes, and pressure gradually increases with ground pressure appears severely, so roadway drivage and support become more and more difficult.

随着开采深度的不断增加，巷道围岩条件也在不断变化，压力逐渐增大，矿压显现剧烈，巷道掘进和支护越来越困难。

Be in in last few years in exploitation process, the pressure that note steam is ceaseless and elevatory, the index of performance of the equipment that note steam of the requirement is higher and higher also, inferior the critical boiler that note steam received wide application.

在近几年的开采过程中，注汽压力不断升高，要求的注汽设备性能指标也越来越高，亚临界注汽锅炉得到了广泛的应用。

The samples were taken from the slope of Haizhou Opencast Mine in Fuxin city.The results show that some components,such as the total hardness and sulfate,above-norm seriously in the beginning of the leaching experiment,and then became stable rapidly with the increasing of eluviate volume,and the pH values of eluviation solution more than seven.Haizhou surface mining will effect the groundwater for 20-25 years.

对从阜新海州露天煤矿岩质边坡取得样品的淋溶实验表明：淋溶初期总硬度、硫酸盐等组分严重超标，各组分随淋溶总体积的增加迅速趋于稳定；淋溶过程中pH＞7，淋溶液偏碱性；海州露天矿开采会对地下水影响20～25 a。

The difference in antidisarrangement capacity of geological environment det ermines that there are different enduring capacities against underground mining in different coal mining areas .

在不同构造条件的煤矿区，地质环境的抗扰动能力不同，因而对地下开采的承载能力也就不同。

The Xuyang base consists of the following factories or workshops: coal mine exploitation and processing, ion-exchange membrane caustic soda, polythene by using calcium carbide ethyne method, thermal power workshops, cement and other assorted industries.

绥阳基地主要由煤炭开采与加工、离子膜烧碱、电石乙炔法生产聚氯乙稀、热电联产动力车间以及水泥和其他配套产业组成。

Enables potentially exploitable programs and/or suspicious executables to be run in a safe, virtual environment.

使潜在的可开采程序和/或可疑的可执行文件将在一个安全，虚拟环境中运行。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
