This paper introduced the cable anchor support technology under the situation of compound roof for Yongxia mining area, analyzed the principle of anchor rod with cable anchor , and made a declaration for the support parameters.

介绍了永夏矿区复合顶板条件下煤巷锚网索支护技术的情况，分析了复合顶板条件下锚杆加锚索支护的原理，并对支护参数进行了说明，对类似条件下的巷道支护具有较强的指导意义。

On the condition of thermal contact metamorphism, clay minerals in coal are changed into andalusite .

无烟煤中红柱石是煤中粘土质矿物经热接触变质作用形成的。

They use biomass fuels like wood, crop waste, animal waste andor coal.

他们使用生物燃料如木材，庄稼废弃物，动物废弃物或煤。

XRD revealed that diffraction angle of 002 peak did not change obviously, while by contrast, L a and L c decreased by loading with Fe2O3, indicating decreasing degree of graphitization for microcrystalline structure of char.

由XRD可知，Fe2O3没有使得煤样半焦的002峰衍射角发生明显变化，但使 L a和 L c参数明显降低，说明半焦的微晶结构石墨化程度降低。

Higher anhydrite and hematite content and lower portlandite content would result in lower ash fusion temperature.

一般情况下，煤灰中氢氧钙石含量低，硬石膏和赤铁矿含量高的煤，灰熔融温度较低。

The content of anhydrite and calcite is lower. The content of anhydrite will increase with the addition of flux CA while the content of calcite will decrease.

煤中添加助熔剂CA后，煤灰中硬石膏含量增加，并且随着助熔剂CA量的不断增加，方解石含量在不断减少，硬石膏含量在不断增加。

Anorthite at high temperature lowers the ash fusion temperature.Key words:coal ash; mineral features;infrared spectrum;X-ray diffraction XRD

利用X-射线衍射和红外光谱从矿物学角度揭示煤灰熔融特性的差异，为高灰熔点煤在气化炉中有效利用提供基础数据。

Investigating result indicates that forecast resources of oil shale amounts to 30×10^(-8)t to convert into shale oil is 1.8×10^(-8t and identified resource of oil shale amounts to 5×10^(-8)t to convert into shale oil is 0.3×10^(-8t. Resources of oil shale, mostly, distributed in middle-Jurassic. Oil shale and coal are intergrowths in here. The structures of oil shale diggnings are simple. Antetype basin is inland lake basin among mountains.

现已查明，该地区油页岩预测资源量至少约30亿t，折合页岩油约2亿t，现已探明油页岩资源量为5亿t，折合页岩油0.3亿t；该区油页岩主要赋存于中侏罗统，与煤共生，油页岩矿区构造简单，原型盆地经恢复为一侏罗纪内陆山间沉积盆地。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
