研究了地质因素对安平、西庄和义堂探区烟煤洁净性的影响。从煤质和可洗性两个方面对洗选潜力进行了评价。利用制图和地理信息软件绘制了具有不同清洁潜力的资源分布图。为明确影响煤炭资源洁净度的地质因素，结合3个勘查区的地质背景，总结了不同洁净度煤炭资源的分布情况。其结果如下：沉积环境可能在影响煤的洁净度方面起很大作用，但它可能不是唯一的因素。在易于产生黄铁矿的环境中形成的煤可以比在更易于产生有机硫的沉积环境中形成的煤具有更好的可清洁性。与沉积环境的影响相反，局部结构（例如，褶皱、断层和陷落柱）通常被认为对具有不同清洁潜力特征的煤的分布几乎没有影响（如果有的话）。
The effects of geological factors on the cleaning potential of Chinese bituminous coals from Anping, Xizhuang, and Yitang exploration areas were studied. The cleaning potential was evaluated in terms of coal quality and cleanability. Distribution maps of resources with different cleaning potentials were prepared using mapping and geographical information software. To identify the geological factors responsible for the cleaning potentials of coal resources, the distribution of coal resources with different cleaning potentials was summarized with regard to the geological setting of the three exploration areas. The results are as follows: The depositional environment may have a large role in affecting the cleanabilities of coals, but it may not be the only factor. Coal which formed in an environment prone to producing pyrite can have a better cleanability than coal formed in a depositional environment that is more prone to producing organic sulfur. In contrast to the effects of depositional environment, the local structures (e.g., folds, faults, and collapse columns), where present, are generally considered to have little, if any, effect on the distribution of the coal with different cleaning potential characteristics.
