开采量

Monazite, rutile, phosphorus and yttrium ore, tantalum and niobium ore, zircon, ilmenite and exploitation of the reserves volume ranks first in the country, Yunfu pyrite is China's largest reserves of pyrite in the sulfur content of the highest in a large-scale mine.

独居石、金红石、磷钇矿、钽铌矿、锆英石、钛铁矿的储藏量和开采量均居全国首位，云浮硫铁矿是中国硫铁矿中储量最多、含硫量最高的一座大型矿山。

The groundwater system is numerically simulating calculated and forecasted by using the internationally standard software Visual Mudflow.

并预报了2006年减少开采量后地下水水位的变化，为研究区地下水资源的合理开发利用提供了科学依据。

One method of preventing seawater intrusion is to reduce offtake to a planned level.

防止海水入侵的一种方法是减少开采量使其达到设计的地下水位标高。

The function can be used to calculate gas volume produced from gas hydrate wells and to evaluate the recoverability of gas hydrate reservoirs.

该函数可以用于天然气水合物井气体开采量的计算及对水合物储层可开采性评价。

He expresses, searching stone to oil deposit hides and increase exploitation to measure is one of element that development of White Russia nation plans.

他表示，寻找石油矿藏和增加开采量是白俄罗斯国家发展计划的要素之一。

Considering the 45-days' zero-flow of the river, the pumpage attenuation of seepage wells was calculated.

在考虑河流持续断流45d的情况下，计算了断流条件下渗流井出水量的衰减过程，在此基础上，确定了悖牛川陕西段河谷区地下水渗流井开采方式新增允许开采量。

Then the sustainable development of Qitai artificial oasis was discussed. Researches showed that the oasis development has gone through three phases: The first was harmonic stage before the middle of 20, the oasis developed according to water resources. The second was unharmonic stage from 1950's to 1980's because of unreasonable policies, that is cultivated area enlarged rapidly and water resources exploited backward. As a result, land output was lower, and environment destroyed heavily. The third stage is after 1980's, the new fragile balance between oasis and its environment was established on the base of the more and more ground water utilization.

研究认为奇台人工绿洲人地关系发展经历了三个阶段：第一阶段是20世纪50年代以前，&以水定地&的相对协调发展时期；第二阶段是20世纪50-80年代人地关系发展失衡时期，人工绿洲迅速扩张，水资源开发滞后，耕地因缺水灌溉而成为低产田，环境破坏严重，人地发展失衡的原因是政策因素；第三阶段是20世纪90年代以来人地关系脆弱平衡时期，决定其平衡的因素是不断增加的地下水开采量。

The net rent approach and user cost approach are the main theories to calculate the serf-value depreciation of unrenewable resources.

虽然它们是在一个相同的思想指导下的非再生资源折耗值测算的方法，但由于使用者成本法对处理存在不断变化的开采量、存储量的情况能运用自如，并且使用其计算的资源价值折耗值也相对稳定等。

Then, basing on the practical problems of the studying area-the thickness of aquifer is little, the capability of depositing water is finite, the Quaternary loose stratum directly superimposes the bedrock strong breeze girdle, the writer thinks it is difficult to answer for the water use of the polyvinyl chloride project by the centralized tube well pumping.

根据研究区含水层厚度小、储水能力差，第四系松散层直接叠加在基岩强风化层之上的具体特点，认为管井集中开采难以满足聚氯乙烯工程的需水量要求，采用集水廊道最大限度地激发河流对地下水的补给，是在这一地区获得较大开采量的有效方式。

According to Rio Tinto, the Simandou project will have an annual production of 70 million tons, and could be expanded to 170 million tons, with targeted mineralisation of between eight and 11 billion tones.

根据力拓公司资料，西芒杜项目预计初期年开采量为 7，000 万吨，其后有可能增加至 1.7 亿吨，而目标矿石量达到 80-110 亿吨。
