可开采的

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。

China has more than 120 resource-based cities, but after decades and even hundreds of years of mining, because of the natural resources irrefragable and can be depleted, including more than 50 resources-exhausted city belongs to, such as liaoning fuxin, jilin LiaoYuan, gansu, silver etc.

翻译下面一段话，水平高的来，在线翻译的别来烦中国有120余座资源型城市，但经过数十年、甚至上百年的开采，由于自然资源的不可再生性和可耗竭性，其中有50余座属于资源枯竭型城市，如辽宁阜新、吉林辽源、甘肃白银等。

The High-Water-Content and Quick-Setting Materials are a new kind of cement with many unique properties: 1. high water content. 2. quick setting and strengthening. 3. long pumpability time. 4. good mechanical properties. 5. the property of re-developing strengthen after ultimate loading.

高水速凝材料是为适应煤炭开采技术的发展需要而研制出的一种新型固体胶结材料，它具有许多独特的优点：①水用量大；②速凝早强：③可泵时间长；④良好的塑性特性；⑤极限荷载后强度再发展性能。

The experimental results show that 1 the charge density coefficient used in the experiment is suitable; 2 the power of explosion is balanced and fully used; 3 the diameter of broken strip of the long hole standing shot in kaolin mine is about 100~150 mm and the rock bodies in the broken circle are debris; and 4 the diameter of the crack strip is about 700~800 mm.

结果表明：试验采用的装药密集系数的确定较适宜，均衡充分利用了爆炸能；高岭土深孔松动爆破孔的破碎带直径大约在100~150 mm，圈内岩体呈碎屑状，裂隙带直径约在700~800 mm；采用加强松动爆破可解决高岭土机械化开采存在的难题。

The price of oil, from the hole in the ground to the spigot has gone crazy.

意思是：从地下开采出来的原油一直到放在油箱里可供取暖的油的价格全都涨疯了

In the oil-gas fields with high exploitation degree, time-lapse seismic technology can be used to predict the exploitation of oil reservoir and the distribution of remaining oil, and to enhance the oil recovery.

在开发程度较高的油气田，可以利用时移地震技术对油藏的开采和剩余油分布情况进行预测，提高油田的采收率。

Some examples are given. Some methods and fruits of the tech-economic evaluation for mining projects are used as reference. The re-evaluation of mineral resource is briefly introduced. It is detailed to convert the mining flotsam into resource. The paper presents a new method, comprehensive index method, to evaluate the actualization degree of wasteless mining.

文中借鉴了矿山项目技术经济评价方面的方法与成果，对矿产资源的再次评价及矿山废料资源化评价进行了讨论：提出了应用综合指数法对无废开采实现程度进行评价的理论体系；应用神经网络系统对矿业可持续发展进行评价，建立了相应模型及标准。

Wasteless mining is a main measure for the realization of the mining sustainable development The paper gives the definition for wasteless mining. The treatise discusses the significance, realization conditions and ways for wasteless mining.

文中对无废开采这一实现矿业可持续发展的最重要途径从其概念、意义、实现条件及实现途径进行了系统的论述，并给出了相应的实例。

No amount of resource extraction beyond what the planet, over millions of years, slowly replenishes, is sustainable.

地球上没有更多的资源开采，几百万年后才慢慢的补充，&可持续发展&是矛盾的。

In this paper,based on field investigation of Kiruna mine,Sweden,and strata control rules,block Y28 on level 632 in the mine is designed and modeled by means of the computer aided design system with strata control rules,and some of conclusions on strata control and computer aided design in stope are drawn.

根据瑞典北部Kiruna矿的现场调查，采用考虑岩层控制规律的CAD系统，对该矿632水平Y28采区进行了设计模拟，得出了如下结论：1.CAD设计中必须考虑岩层控制规律，与大规模开采有关的问题可通过考虑岩层控制规律得到改善。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
