Though the contents of trace elements in coal are very low, environment pollution caused by trace elements has been an inarguable fact At present, more researches lay particular stress on the occurrence during coal combustion, and several about coal gasification. The researches about trace elements in fluidized bed gasification are much less, saying nothing of pressurized fluidized bed gasification.

目前国内外研究更多的偏重于燃煤过程，对煤气化过程中微量元素迁移规律的研究较少，关于流化床气化炉型的文献更少，涉及加压煤气化过程中微量元素迁移规律的研究几乎没有。

The strata are Triassic Xujiahe group sand-shale stratum which containing coal layer. It is nearly three-century history about the coal layer exploitation. In that time, because of the outdated technique and inorganization, the coal caves have the characteristic of randomicity, concealment, universality, no obviously regularity and the small scale for single cave.

坝区地层为三叠系须家河组砂页岩含煤地层，煤层的开采已近300年历史，由于当时开采技术落后、无组织性，导致煤洞具有随机性、隐蔽性、广泛性、单洞规模小、无明显规律等特点。

The results show that the Lande factors are 2.002~2.003, which have little change, and that of coal from Zhangji coal mine are little larger than that form Baijigou coal mine. Small particle size, high oxidation temperature and long oxidation time can lead to high corventration and high line height. However, the trend of line width is dispersive.

结果表明：煤自由基因子在2.002~2.003之间，变化不大，张集矿肥煤的因子值稍大于白芨沟无烟煤；煤体粒径越小、氧化温度越高、氧化时间越长，煤自由基浓度越大；线高的变化趋势与自由基浓度变化趋势基本一致；线宽的变化趋势呈分散性。

Principles of the method are that all ash composition comes from the minerals and clasts in coal seams, so it is possible to reversely infer the sorts, contents and grading law of the minerals and clasts of coal seam from the sorts, contents and grading law of ash composition ,in advance to judge the coal forming environment.

其原理是：灰成分与煤中矿物质种类与含量具有成因上的相关关系--据SiO -Al2 O3 端元特征，可以判断介质的总体运动方向；由CaO -MgO端元特征，可以判断泥炭沼泽受海水影响的程度；由Fe2 O3 -SO3 端元特征，可以判断聚煤环境的氧化还原条件。

It is directly related to the development and exist of the enterprise. Seen from the dog-eat-dog market and the states of the coal enterprise. It is a logjam way to improve the price and increase the output of coal, but there is only way to improve the economical efficiently of coal through controlling the cost. But, on controlling of the cost, there is a great limitation in traditional product-centered cost calculation system.

从激烈的市场和煤炭企业自身的情况看，煤炭企业提高价格和提高产量的方法是行不通的，只有通过内部自身进行有效的控制成本才是提高煤炭企业经济利益的根本途径，而在控制成本方面，传统的以"产品"为中心的成本核算体系存在很大的局限性。

Judged from coal rank, combustion characteristics and kinetic analyzing results, the stone coal should be classed as a high rank and maggy anthracite coal.

从燃烧特性参数和反应动力学参数判断，石煤属于高变质的无烟煤。

According to the viewpoint of coal petrography,the geologic and formation condition in Fujian, factors and types of coal metamorphose are described, the results show that coal metamorphose in Fujian belong to multivalence and superposition .

从煤岩学角度并结合福建省的地质、构造条件，阐述了影响福建省煤变质的因素和类型，研究表明，福建煤的变质应属多元、叠加的结果。

In this paper, Petrographical coal blending and predicing coke quality were done using 15 kinds of normal coal, by 40Kg coke oven and using microphotometer and polarized light microscope to check the quality of the coke, on the basis of investigation of quality, stability and price of about 30 kinds of coking coal recently used by ANGANG GROUP.

本文在对鞍钢近年使用的约30种炼焦煤的质量、稳定性及价格充分调研的基础上，选择了15种常用煤为实验煤种，以40Kg实验焦炉为炼焦手段，以显微光度仪和偏光显微镜为煤岩检测工具，开展了煤岩配煤与预测焦炭质量的研究工作。

Before design of this program , the researchers and engineers in the coal mine obtain the data with detector and by drilling, prospecting tunnel.Then the researchers synthetically analyze the geology data such as the coal seam construction,dip angle,thickness of coal mine.
