本工作是在分析了全国最新煤炭资源潜力评价资料和任德义、唐修义、陆旭坤等发表的大量煤炭资源潜力评价资料的基础上，结合前人提出的煤炭资源清洁潜力评价方法，对煤炭资源清洁潜力进行了评价。研究发现，以往的煤种分级方法只是按照原煤或洗选煤进行分级，没有充分考虑煤洗选前后元素的变化。有些元素可以通过洗煤或其他方法去除，有些元素甚至可以在洗煤后富集。为此，本文定义了一个新的洁净度参数，并推导了其计算公式，以确定煤炭资源的洁净潜力。洁净度是以煤中各指标有害元素的去除率为基础的综合指标。煤的洁净潜力与其洁净度成正比。可清洁性值越高，清洁潜力越好，反之亦然。
This work is based on analysis on large numbers of coal data such as the latest national coal potential evaluation data and previous data published by REN Deyi, TANG Xiuyi and LU Xukun, and the evaluation methods of clean potential of coal resources proposed by predecessors. It is found that previous method rank coal is only in accordance with raw coal or washed coal, which fail to take full account of the changes in elements before and after coal washing. Some elements can be removed by washing or other methods, and others may be even enriched after the coal is washed. For this reason, this work defined a new parameter of cleanability and developed its calculation formula to determine the clean potential of coal resources. Cleanability is a comprehensive indicator based on the removal rate of each indicator harmful element in coal. The clean potential of coal is proportional to the value of cleanability. The higher the cleanability value is, the better the clean potential is, and vice versa.
