The generation of air-borne dust from unpaved haul roads of opencast mines can be effectively suppressed by mixing dust-suppressant chemicals in spraying water. Before applying any suppressant, it is necessary to evaluate its physical and chemical properties to ensure safety of human beings, as well as that of the working environment. Studies of physico-chemical properties can predict quality, effectiveness in controlling air-borne dust, and its effect on flora and fauna. The neutral character of chemical solution, penetration of water in the road bed, fi re hazard, evaluation of poisonous gas at high atmospheric temperatures, degradation of chemical structure over time, presence of toxic metals, and effect on human health, plants, and aquatic life are to be studied. The scientific study described below provides an effective methodology for evaluation of physico-chemical properties of dust-suppressant chemical and its application on unpaved haul road of opencast mines.
