【摘要】 在试验巷道中，试验了风速在（０ ．７ ～２ ．１） ｍ／ｓ 的状态下的风流排尘能力，考察了不同风速下粉尘浓度和粒度的沿程变化规律，定量分析了风流排尘能力与风速、尘源位置的关系。更多还原

【Abstract】 The dust removal capacity was tested under air velocities ranging in 0.7～2.1m/s in an experimental gallery. The changing rules of dust level and particle size under different air velocity were investigated along the gallery, and the relationship between dust removal capacity of air flow and air velocity and location of dust source was quantitatively analyzed.更多还原
