344 The tests conducted are aimed at evaluating the effectiveness of alternative reagents. The experiments were performed in laboratory and on field in a real production environment. Three products designed for dust control by forming a surface stabilizing crust were tested (Table 1) Table 1 - Comparison of dust control reagents Reagent Type Features Innocoat 1080 Organic Biopolymer High resistance, elastic skin Innocoat 1038 Organic Formula Average stability, relatively easy to apply Innocoat 1090 Polymer Reagent Good fixation, poor moisture resistance Control samples were treated with lime milk and water for comparative evaluation. Laboratory tests After preparing and treating the samples (wetting their surface) – Fig. 1 – they were left to dry under atmospheric conditions, after which they were tested by blowing with compressed air – Fig. 2.
