摘要
推导了落尘的沉积模型，提出了落尘聚集体、落尘凝结体的概念。通过对落尘颗粒间四种主要内聚力以及气流浮力的量级分析，指出矿井条件下抑制落尘颗粒二次飞扬的前提是使尘粒得到充分的湿润。
A deposition model of settled dust is inferred.The concept of coagulaion and coherence of the settled dust is suggested.By gradation analysis of four main cohesion forces and floating force in the air-flow,it is indicated that the prerequisite for controlling the secondary flying of the settled dust in mine is to thoroughly wet the dust. Secondary flying of two aggregations has been experimented.
