Direct Mensuration Method of Mine Dust
-
摘要: 提出了采用粘塵劑、多面空心球、二氯甲烷實現一次多點采樣,用Masyersizer X分散度僅直接測定粒度分布的新方法,并用它測定了礦井巷道粉塵濃度和粒度情況.對漳村礦某一回風巷道斷面的粉塵分布情況分析證明此方法可靠.Abstract: A new direct mensuration method of dust granularity distribution with Masyersier X dispersive degree instrument is put forward. This method was implemented by gathering data in many spot once with sticking-dust agent, polyhedron empty ball and CH2Cl2. Dust concentration and granularity of mine laneway were determined. Dust distribution condition of a intake cross-section in Zhang Chun mine was analyzed.
