摘要
本文应用分形几何理论，研究了采煤工作面煤尘粒度分布的分形特征．研究发现，煤尘粒度分布具有很好的分形结构，其粒度分布可用分维值定量地描述。
With the fractal geometric theory, this paper analyzes the fractal characteristic of the coal dust size distribution in the longwall face. It is found that the coal dust size distribution has a very good fractal structure, and the size distribution of the coal dust can be characterised by the fractal dimension value. It is necessary to study the coal dust size distribution in order to provide more effective and scientific basis for selection of the dedusted method and device.
