Shuangbai County teak coal mine rock Adit sub-head coal and gas outburst accident occurred.

双柏县麻栗树煤矿岩子头矿井平洞发生煤与瓦斯突出事故。

The new method integrated the processes of methane/steam reforming and coal combustion.

新方法将天然气/水蒸汽重整反应过程和煤燃烧过程整合起来，通过两个化学反应过程的耦合，发挥了天然气和煤的各自特点，实现了天然气和煤的高效清洁利用。

The top coal fracture is described distinctly under the condition of different roof span and mining technology parameters. Through orthogonal experiment of numerical simulation, the rational pretreatment span of hard roof is determined, and the rational working resistance of support is selected also. As a result: the hard roof is effectively controlled not only to protect the working face but also to promote the caving of hard top coal to increase the recovery ratio.

在有效控制坚硬顶板的基础上，利用数值模拟正交试验法，研究了采高、采放比、支架阻力、放煤步距等工艺参数对顶煤压裂效果的影响规律，从而对工作面工艺参数进行优化；并根据实验所得放煤方式对块体顶煤的适应性规律，选择&两硬&综放面的放煤工艺，从而形成了系统、完善的&两硬&条件综放工艺。

Then based on analysis of on-line data,the work condition with shut-up of one coal feeding system is taken as one important work condition with more frequency.Then the number of working coal feeding system and load is introduced into model. The system is analyzed based on DHA framework,and MLD model is produced with HYSDEL programming language.

根据对现场运行数据的分析，确定给煤线断煤是运行过程中一种发生频率较多的工况，将正常运行的给煤线数目和负荷作为非连续参数引入模型，对模型进行了基于DHA框架下的混杂系统分析，并利用HYSDEL语言建立了MLD模型。

Numerical simulation results show that, after No.16 coal seam has been mined, the subsidence of the No. 15 coal seam does not reach 750 mm, half of its thickness. Except the area corresponding to the face end of the No. 16 long wall coalface, the No.

模拟结果表明，先采己16煤后，己15煤的倾斜值即其台阶下沉量比较小，未超过煤厚之半(750 mm)，除工作面两端头对应区域外，煤层表现的很连续。

Coal is an organic rock which is sensitive to geological environmental factors such as temperature and pressure. Various tectonothermal events of the geological evolution must have caused a series of changes in physical, chemical structures of coal and thus formed different tectonically deformed coals.

煤岩是一种对温度、压力等地质环境因素十分敏感的有机岩，地质演化过程中的各种构造热事件必然导致煤岩发生一系列物理与化学结构的变化，并形成不同类型的构造煤。

In order to widen selective range of coals in cement kiln, in this thesis, the research of ignition characteristics, kinetics and microstructure to different quality coal is carried on, which offer the foundation theoretical for the low quality coal used in New Dry Process kiln craft.

为了拓宽水泥工业用煤的选择范围，本文结合干法水泥生产过程，进行了针对分解炉内不同质煤的着火特性、动力学和微观结构问题的研究，希望能为劣质煤在干法水泥生产中应用提供理论依据。

To explain the reason for the abruptly thin thickness of coal in Hole T4, 3D exploration technology is used in loess region firstly.

从钻孔资料分析、测井曲线对比、黄土塬区三维地震勘探以及综合地震地质解释等几个方面，对T4孔的煤厚变化原因进行了综合分析与解释，查明了T4孔煤厚变化的原因以及区内煤厚变化趋势。

The liquefaction equipment in Germany is built at Bottrop,Ruhr district with the scale of 200 tons per day.

德国的煤液化装置建在鲁尔区Bottrop，规模为200吨／天，煤液化试验用煤量累计16.6万吨。

This year, in the "largest port led to large logistics" of the development strategy, the big push forward the construction of the coal terminal, are: Huaneng Power Plant Haimen 150,000-ton coal pier and richness of plant Haimen 70,000-ton coal terminal building synchronization advance; Masan Port 35,000-ton coal terminal expansion project is also speed up the process.

今年来，在&以大港口带动大物流&的发展战略中，当局大手笔推进煤码头建设，有：华能海门电厂15万吨级煤炭码头和丰盛海门电厂7万吨级煤码头的建设同步推进；马山港区3.5万吨级煤码头扩建工程建设也在加快进行。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
