煤炭资源开发战略问题分析

煤炭是应用较为广泛的能源形式,属于不可再生的战略资源,我国的煤炭能源储备丰富,但随着改革开放以来的大力开发利用,煤炭的储备已经有了大幅度的减少,本文主要探讨了煤炭资源开发过程中的战略手段,提高我国的能源供给质量。

An Entrapment Model of Water Flow on Fine Coal Flotation

Effect of entrapment of water flow on fine coal flotation was studied. The relation between constant of water flotation rate and flotation time was investigated and the water recycling model determined. The entrapment model of water flow about the relation between the recovery of fine particle and that of water in concentration was established. Finally, the equation about ash in fine clean coal at any time was derived by introducing a de-ashing coefficient.
