Second, it accomplishes numerical computation at different ignition temperature and combustion time of different coal quality in calciner.

本文的特色在于：一方面，针对水泥分解炉工况，首次在国内系统而全面的研究了煤的燃烧特性及相关规律；另一方面，实现了分解炉内不同煤质的着火温度和燃尽时间的数值计算，从而使水泥分解炉内，煤的燃烧理论研究朝着工程应用的方向迈进。

Vitrinite and desmocollinite have a relatively low potential of hydrocarbon generation. The stable carbon isotope composition of their pyrolysis oils is heavier than that of sporinite, cutinite and oils derived from coal-bearing strata. It seems that they cannot be major macerals to generate oil, even if they occupy a majority of proportion in the organic matter of coal and coaly shale, and that they can be good gas-prone macerals at the stage of high-maturity to over-maturity.

镜质体和基质镜质体的生油潜力相对较低，其生成的液态烃类的碳同位素组成比一般煤系原油重得多，而且这些组分本身对液态烃具有较强的吸附力，尽管其在煤系有机质中所占的比例很大，仍然难以成为生成液态石油的主要显微组分，只能在高成熟演化阶段成为良好的生气显微组分。

The coal and coaly organic matter are believed mainly to be hydrocarbon souce of the basin in the middlelow Jurassic of the Turpan-Hami basin.

吐哈盆地中下佛罗统煤及煤系有机质被确认为该盆地的主力烃源岩。

Mature, synrift lacustrine shales of Eocene to Oligocene age and mature, late rift coals and coaly shales of Oligocene to Miocene age are source rocks for oil and gas in two important petroleum systems of the onshore and offshore areas of the Northwest Java Basin. Biogenic gas and carbonate sourced gas have also been identified. These hydrocarbons are trapped primarily in anticlines and fault blocks involving sandstone and carbonate reservoirs.

爪哇盆地西北的沿海地区的两个重要的石油体系中，始新世至渐新世的湖泊页岩、渐新世至中新世晚期裂隙煤和含煤页岩是石油和天然气的矿源岩，鉴别出了生物源气体和碳酸盐源气体，这些烃类被圈闭在背斜和断层中，包括沙岩、碳酸盐岩油储。

There are many influencing factors of roadway surrounding rock stability, and which have complexly nonlinear relationship with surrounding rock stability.

影响煤巷围岩稳定性的因素很多，这些因素与煤巷围岩稳定性之间呈现出一种非常复杂的非线性关系。

In this study, we simulated diagenetic alterations under laboratory conditions by thermally treating three different types low-grade coals at 200, 250, 300, 350, 400, 450 and 500℃, yielding three series of coals with differences in parental material and maturation.

本研究选用三种不同类型的未成熟煤，在实验室中于200℃，250℃，300℃，350℃，400℃，450℃，500℃七个温度对样品进行热处理，得到三个系列不同类型和不同成熟度的煤。

According to study on fully-mechanized coal winning machine research, application and type selection,fully-mechanized drivage technology transformation in complicated geological conditions, fully-mechanized coal winning machine matching systems transformation, and high-stress roadway fast support technology, additional benefits due to normal production replacement are ensured.

通过综掘机的研究应用及选型、复杂地质条件下综合机械化掘进技术改造、综掘机配套系统的改造及高应力巷道快速支护技术等研究，保证了正常生产接续所带来附加效益；单进水平逐年提升，在华丰煤矿21603下平巷，煤层倾角25°～26°条件下，创造出薄煤层半煤岩巷月进尺631 m，日最高进尺28.8 m的纪录；随着综掘机的不断引进以及快速掘进成套技术的大范围推广应用，综掘总进尺占煤巷总进尺的比例由2004年的21.45％上升至现今的 62.34％。

These have important academic and realistic value to study the connection between the coal and rock failure and EME, and to prevent and control the dynamic catastrophe of the coal and rock.

这对于搞清煤岩破坏与电磁辐射之间的关系，防治煤岩动力灾害具有重要的理论和实际价值。

The catalysis effect of carbide lime , which is a residue in the ethyne production and has a good sulfur-retention property, on pulverized coal combustion has been studied on a thermogravimetric analyzer.

用热重法研究了不同条件下电石渣的催化煤燃烧特性，发现电石渣对晋城煤的着火温度和固定碳燃尽率都具有一定的促进作用，而且随添加量的增加助燃作用增强。
