利用泡沫控制煤尘已被证明是一种高效的清洁技术。为了研究煤颗粒与泡沫之间的相互作用，本研究通过高速摄像机捕捉到煤颗粒沉降到泡沫上的过程。观察了相互作用过程中泡沫膜的变化以及泡沫体系中煤颗粒的分散情况。结果表明，泡沫膜的变形和破裂是缓解煤颗粒冲击的主要方式。当煤粒粘附在泡沫薄膜上时，它会按照以下路径在泡沫薄膜上滑动：从泡沫薄膜，到高原边界，最后到达顶点。确定了使用泡沫去除煤尘的两个不同阶段。对这两个阶段中作用在煤颗粒上的力进行了数学建模。该研究结果对于深入理解泡沫捕集煤尘过程具有重要意义。利用泡沫控制煤尘已被证明是一种高效的清洁技术。为了研究煤颗粒与泡沫之间的相互作用，本研究通过高速摄像机捕捉到煤颗粒沉降到泡沫上的过程。观察了相互作用过程中泡沫膜的变化以及泡沫体系中煤颗粒的分散情况。结果表明，泡沫膜的变形和破裂是缓解煤颗粒冲击的主要方式。当煤粒粘附在泡沫薄膜上时，它会按照以下路径在泡沫薄膜上滑动：从泡沫薄膜，到高原边界，最后到达顶点。确定了使用泡沫去除煤尘的两个不同阶段。对这两个阶段中作用在煤颗粒上的力进行了数学建模。该结果对于深刻理解泡沫捕集煤尘过程具有重要意义。
The utilization of foam for coal dust control has been proven to be an efficient clean technology. To investigate the interaction between coal particles and foam, the process that coal particles settling onto foam was captured via a high-speed camera in this research. The changes of the foam film and the dispersion of coal particles in the foam system during the interaction process were observed. The results revealed that the deformation and rupture of the foam film are the main modes that alleviating the impact of the coal particles. When a coal particle adhered to the foam film, it would slide on the foam film along the following path in order: from the film, to the Plateau borders, finally arrived at the vertices. Two distinct stages of coal dust removal using foam were identified. The forces acting on a coal particle during the two stages were modelled mathematically. The results are meaningful for a profound understanding of the coal dust capture process using foam.The utilization of foam for coal dust control has been proven to be an efficient clean technology.
