Taiyuan in the "sea of coal" in the central, on the geological reserves of coal, Taiyuan, said "the Department of Taiyuan Coal", the province's seventh largest reserve, Shanxi Coal is the main component of the resource.

太原处在"煤海"中部，地质上称太原的煤藏为"太原系煤"，储量居全省第七位，是山西煤炭资源的主要组成部分。

Therefore of the opinion that if the coal Jinzhong Southern sea channel was launched by Rizhao Port, Rizhao Port of this unique pattern of distribution of goods, coal and ore can be heavy-duty round-trip transportation to import Iron ore and coal exports of a virtuous circle.

不仅如此，以兖矿的煤码头而兴的日照港，腹地现有煤炭生产企业约8000个，其中，年产能力在1000万吨以上的国有重点煤企就有12家，产能高达4.2亿吨。

In the thesis, the cost of generating electricity at rated load was set as objective function to establish the model to acquire the optimum operational parameters of fuel-feeding and air-feeding system.

本文运用锅炉在额定负荷下的发电成本为目标函数，建立了锅炉给煤系统和风烟系统主要运行参数的优化模型，以指导在新煤质下如何调整给煤和给风以达到发电成本最小。

The increase severeness of pollution make people bring forward higher demand for the quality of coal increasingly, especially the content of sulfur.

污染的加重，使人们对煤的品质提出了更高的要求，尤其是煤中硫的含量。

The strength of coal and rock mass can be weakened through deep hole relieving shot, so the ability of energy accumulation is reduced, and a large amount of elastic energy accumulated in coal and rock mass is released, which makes it sure that the elastic energy accumulated in coal and rock mass do not exceed the minimum energy induced rock burst. Simultaneously, electromagnetic emission is used to check out the effect of eliminating or reducing the danger of rock bursts.

通过深孔卸压爆破来弱化煤岩结构的强度，降低其聚能能力，释放所积聚的大量弹性能，使得煤岩体中所积聚的弹性能达不到最小冲击能；同时利用电磁辐射检验强度弱化治理效果，以达到消除或降低冲击危险的目的。

The influence of each strategy on heat economy and safety operation of gas turbine simple cycle was discuss...

结果表明：对于焦炉煤气，方案1的热经济性最高，方案4的热经济性最低，各方案对燃气轮机的安全运行几乎没有影响；对于煤基合成气，方案5的热经济性最高，方案4的热经济性最低，方案1的安全性最差；综合考虑热经济性、安全性和可操作性，对于焦炉煤气，方案1是最佳方案，对于煤基合成气，方案2是最佳方案。

Technology of coal of gush of blast furnace double gun solves blast furnace coal effectively to compare current velocity of the coal fines when rising fast, coal fines and sirocco mix inadequate, cause efficiency of combustion of blast furnace coal fines this technique still can reduce low problem; effectively remove dust the carbolic content in ash, energy-saving to the enterprise decrease platoon and clean production to having active sense.

高炉双枪喷煤技术能有效地解决高炉煤比提高时煤粉流速快，煤粉和热风混合不充分，致使高炉煤粉燃烧效率低等新问题；此项技术还能有效降低除尘灰中的碳含量，对企业节能减排和清洁生产有着积极意义。

In this paper, based on the analysis of the requests and characteristics of the coal slurry system, the author introduces the rese...

本文分析了煤浆系统的特点和要求，在此基础上，采用Monte Carlo方法对煤浆系统的主要物理问题进行了研究和探讨。

In fact, silicon dioxide, aluminum oxide, ferric oxide, calcium oxide and sodium oxide are the main components of coal ash that influence on fouling and slagging.

由于我国煤炭种类繁多，煤中矿物质的成分和含量千变万化，给煤的结渣机理研究带来很多干扰因素，从中找出明确的规律不是一件易事。

And proposes that f value is regarded as the classification quota of hard coal and tectonic soft coal.

并提出将f值作为硬煤和构造软煤的分类指标。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
