When fillings is other materials ( unprocessed montmorillonite , powder coal ash , co - composite of powder coal ash and organo - montmorillonite , co - composite ofcarbonizing calcium and organo - montmorillonite ) in the binder and content of organo - montmorillonite in the binder is five percent decided by tensile - shear experiment , tensile - shear strength of binder is up to tiptop ; at the same time , this paper carries out abrasion experiment , and , by comparison , concludes abrasion property of coating is optimum when content of organo - montmorillonite in the binder coating is five percent , and observes abrasion sample under set 當膠粘劑中填料為其它物質(未處理蒙脫土、粉煤灰、粉煤灰和有機化蒙脫土共復合、碳化鈣和有機化蒙脫土共復合)時,通過拉伸剪切試驗確定膠粘劑中有機化蒙脫土含量為5時,膠粘劑的拉伸剪切強度最高;同時進行了沖蝕磨損試驗,通過比較得出,當膠粘劑涂層中有機化蒙脫土含量達到5時,涂層的耐沖蝕磨損性能最佳,并對沖蝕磨損試樣在掃描電子顯微鏡( set )上進行觀察。

Multi - hierarchical , multimeans , comprehensive and deepened research on the macrofractures , microfractures system and pores system features , capacity of cbm storage and osmosis , adsorption characteristic , as well as physical properties of surrounding rocks of coal reservoirs have been made . furthermore , classifying standard and identifying characteristics for fractures - pores system of low coal rank coal reservoirs in zhungaer basin has been put forward as well . in this process , some routine instrument are used , such as viewing coal mine scene and hand specimen , observing polished section and surface which are made from lump coal and powder coal samples , observing and image analyses under the common microscope ' s transmitted light , reflection light and fluorescence 通過礦井現場、鏡下觀察統計等常規手段,采用多種先進儀器和測試技術展開對煤儲層的裂隙系統與孔隙系統發育特征、儲滲性能、吸附特性及煤儲層圍巖物性特征的多層次、多手段分析,并綜合室內外觀測及前人成果,提出了煤儲層裂隙與孔隙系統的劃分標準與識別特征,分別從宏微觀尺度、定性與定量層次對裂隙與孔隙系統特征及其與煤儲層儲滲性能關系的研究。

Moreover , the system of powdered coal conveying with primary air is the most important tache , whether the distribution of primary air is even or not directly relates to whether the distribution of powdered coal is even or not in all firing implement and nozzles , sequentially directly relates to whether it is hard to take fire , whether the fire is stable , whether there is coking and how about the heat efficiency of the boiler , hi addition , if there is jamming and deflagrate in the system of powdered coal conveying with primary air , severe safety accident can be resulted 良好的煤粉配風是建立合理的爐內空氣動力工況和穩定燃燒的必要條件。而其中一次熱風送粉系統又是最重要的一個環節,一次風配風是否均勻直接關系到煤粉在各燃燒器和各噴嘴中的分布是否均勻,從而直接關系到著火是否困難、火焰是否穩定、局部是否結焦以及鍋爐的熱效率高低。若一次風送粉系統發生堵塞和煤粉爆燃則可能引發嚴重的安全事故。
