该方案主要是由煤斗及煤斗内的给煤滚筒，在给煤滚筒上的闸板和给煤滚筒侧下方的上筛分板，在给煤滚筒的另一侧下方，上筛分板的下方，有至少一个与上筛分板倾斜角度相反的下筛分板。

CFB clean coal power generation technology is a kind of combustion technology for power generation, it is the internal combustion in circulating fluidized bed boiler with coal particles, and at low-temperature combustion furnace conditions add to the amount of limestone achieve desulfurization, denitration cleanliness coal power generation technology.

CFB发电技术是煤清洁燃烧发电技术的一种，它是在循环流化床锅炉内燃用颗粒煤，并在低温燃烧状况下向炉内加入适量石灰石实现脱硫、脱硝的洁净煤发电技术。

With development of economy in our country, demand for resources in especial for altogether coal have increasingly augmented according to the booming market. Though mechanization in the coal industry had been surprisingly progressed by the least 50 years, the technology of blasting engineering has been importantly seized on exploiting coal yet, especially, aiming at statue quo of disbalance development in technology and science.

随着我国经济的快速发展，市场对能源的需求尤其是对煤炭的需求大幅度提高，虽然煤炭生产综合机械化水平不断的提高，但是采用爆破技术采煤仍然占有一席之地，尤其针对我国目前技术水平发展不平衡的现状，对于赋存大量倾斜煤层和复杂煤层环境条件，开展爆破开采技术优化的研究是必要的也是急需的。

Its function is on one hand to buffering the coal coming from the dumper and coal pile, and on the other hand to mix coal.

它们的作用一方面是缓冲从翻车机和煤堆来的煤，另一方面是混煤。

The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.

总空隙主要由小孔孔容构成，小孔孔容占了50%以上；镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性，说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主，空隙开放的次序为暗煤-亮煤-煤样-镜煤，其他盆地则为半封闭和细瓶颈空隙 4、随压力增加，煤对气体的吸附量增加，煤中所含游离气的量随之减小；随温度增加，煤对气体的吸附量减小，而煤中所含游离气的量随之增加；在相同的温压条件下，同是长焰煤的样品，吸附量在孔容中所占的比例随镜质组含量增加而增加。

The results show that coal mining spoils contributed heavy metal pollution of the coal mining soil and heavy metals accumulation is caused by coal mining spoils piled up, catamorphism and eluvium.

由此可见，矿业开采活动对当地土壤重金属含量有一定的贡献，但不同的重金属元素在矿区土壤中的积累表现出差异性。

Coal seam is entia of coal-forming material components, characteristics and forming environment, coal lithotypes, chemical composition etc.

煤层是成煤物质成分、特征和形成环境的统一体，煤岩组分、煤的化学组成等是煤层物质成分和形成环境的体现。

Based on the concept of averaging electromagnetic field, the optical constants of Goodwin synthetic ash, Chinese Qitaihe coal ash and Russian ash Br-1 were calculated by Maxwell-Garnett and Bruggeman effective medium theory. Computational results show that, for the synthetic coal slag, the optical constants estimated by EMT consist with the experimental values, but for the coal-ash produced in combustion, the optical constants estimated by EMT using industrial analytical species deviate far from the experimental values.
