目前国际上评定煤炭可能性的方法有多种,但不论哪种方法都不能科学地反映选后各产品相互污染的程度。因此,关于中国煤炭可选性如何评定,广大选煤工作者都非常关心,希望能有一个结合中国实际情况的煤炭可选性评定标准,作为生产管理、科学研究和设计的依据。为此谈一些看法同大家一起讨论。一、影响煤炭可造性的主要因素在重力选煤过程中,影响煤炭可选性 At present, there are many ways to assess the possibility of coal in the world, but neither method can scientifically reflect the degree of mutual pollution of the products after the election. Therefore, regarding how to evaluate the coal selectivities in China, the majority of coal preparation workers are very concerned about it. We hope that there will be a coal selec- tivity assessment standard based on China’s actual conditions as the basis for production management, scientific research and design. Talk about some ideas to discuss with you. First, the main factors that affect the manufacturability of coal Gravity coal preparation process, affecting the coal selectivity
