| 摘 要： | 基于我国煤层特性和煤层气井的排采工艺，分析了煤层气生产过程中产生煤粉的原因。综合考虑煤粉成因机制、产出来源、对生产的影响等因素，提出煤粉的成因机制一产出位置综合分类体系。煤层的自身性质是煤粉产出的基础，而工程扰动是煤粉产出的诱因。以煤粉综合分类体系为基础，讨论了合理控制煤层气排采过程中煤粉产出的措施。

| Abstract: | In consideration of coal seam characteristics and CBM drainage technology in the country, analyzed coal fines producing causation during the CBM production process. Comprehensively considered factors of coal fines genetic mechanism, origin site and impact on production, put forward coal fines genetic mechanism and origin site integrated classification system. The nature of coal seam per se is the basis of coal fines generation, while the engineering process disturbance the inducements. Based on coal fines integrated classification system, discussed the rational measures to control coal fines generation during the CBM drainage process. |
