传统上，煤炭都是在开采地燃烧——尤其是用以取暖和发电的动力煤或电煤。
Traditionally, coal is burned near where it is mined - particularly so-called thermal or steaming coal, used for heat and electricity.
理由是煤燃烧过后省些的煤灰含有放射性元素，尤其是铀和钍。
The reason is that the ash left over when coal is burned contains radioactive elements, notably uranium and thorium.
煤炭分两种：动力煤(用来发电)和冶金用煤(在某些金属的生产过程中使用，尤其是钢)。
There are two kinds of coal: steam coal, which is used to generate electricity, and metallurgical coal, which is used in the production process for certain metals - especially steel.
实验结果表明，BET的浮选效果要优于普通煤用浮选药剂，尤其是用于高硫煤的浮选时，它有很强的选择性。
The results manifested that the floatation effect of BET is better than that of other common floatation reagents and has a higher selectivity especially in high-sulfur coal sample floatation.
因此非常有力于炼油企业，尤其对成本相对较低的煤直接液化项目非常有利。
So it is very benefit for oil refining enterprise, especially for the project of directly liquefying coal with lower cost.
煤甚至于比石油的污染还要大，尤其是考虑到全球气候变暖的情况。
Coal is even more polluting than oil, contributing even more to global warming.
另一方面，有限的和不可恢复的能源，尤其是化石燃料，比如石油和煤不能为我们提供足够的供应。
On the other hand, limited and unrecoverable energy, especially fossil fuels like oil and coals, can not offer us adequate supply.
煤种适应性强，尤其适用于焦油含量高，产气量大的烟煤。
It has good coal adaptability and is especially suitable for soft coal that has high tar content and big gas output.
总结了高炉喷煤尤其是大量喷煤中未燃煤粉行为的研究结果。
The studied results of behavior of unburnt pulverized coal in process of PCI in BF are summarized.
结果表明，电化学调浆不破坏煤的结构，经过电化学调浆浮选，能有效的脱除煤中硫、尤其是黄铁矿硫。
The result show that the pyrite in coal is the oxidized FeSn, and can be suppressed by electro reduction.
应用该软件可进行钢球磨煤机贮仓式制粉系统设计计算和校核计算，尤其适用于电厂变化煤种、运行方式或设备偏离设计值时的校核热力计算。
The application shows that this software is applicable for the design or check calculation, especially for the varying of coal type or operation mode.
顶煤的运移与垮落，尤其是内部微观裂隙的扩展，与其直接顶和老顶岩层的活动规律密切相关。
The movement and breakage of top coal, especially its internal micro-fracture extension, are closely related to the movement regularity of its immediate roof and main roof.
煤炭分两种：动力煤（用来发电）和冶金用煤（在某些金属的生产过程中使用，尤其是钢）。
There are two kinds of coal: steam coal, which is used to generate electricity, and metallurgical coal, which is used in the production process for certain metals especially steel.
热力耦合作用和热解产气是影响煤体变形的关键因素，尤其在高温阶段，热解产气对变形起到主控作用。
