摘要
为建立一个完整的煤洁净程度评价体系,探讨选用煤的灰分、硫分、部分有害微量元素(包括元素的含量、挥发性)、赋存状态、淋滤特征以及煤的可选性为评价指标,根据有害微量元素的毒性来确定各微量元素的权重,并基于模糊综合评价法建立了一个洁净煤、一般煤和不洁净煤的三级煤洁净程度评价系统。文章还应用此系统有效地评价了涡阳花沟西10煤层煤的洁净程度,评价结果表明:涡阳花沟西10煤层煤属于洁净煤。
In order to build a completed clean degree evaluation system of coal,the ash and sulfur contents,some hazardous trace elements including its contents,volatilities,occurrences and leach-ability from ash,and wash-ability of coal were selected as evaluation index,the weights of trace elements were established by its toxicity,and an three degree evaluation system which included clean coal,middle coal and dirty coal was built based on fuzzy comprehensive method. Ten coal samples from coal-bed No.10 at Western Huagou were assessed using this evaluation system. The result shows that: All the coal samples were clean coal. The evaluation system is scientific,rational,effective and guiding significance for the assessment of clean coal degree.
