“…Out of the listed methods the foam one has a number of advantages: minimum fluid consumption, big surface of interphase interaction of dispersed fluid and dust particles, prevention of over moisturizing of technological raw material, possibility of efficient use on mobile sources of dust liberation and formation, and also under the conditions of negative temperatures of air environment, which, in the end, provides for the possibility of considerable increase of efficiency of dust suppression, especially of finely-divided, most pneumonoconiosis-dangerous dust fractions [6,[9][10][11][12]. As a rule, foam method is used for spread sources of dust release (different types of transporters: belt, bucket, auger-type).…”
