  • A simple statement about dust hazard and the mechanism of roadway dust induced by haulage loads in an open pit were analyzed. Based on the theoretic results, a concept for eco-typed dust control and a recipe of roadway dust suppression were introduced. The dust suppressor characterized by adhesion, moisture-absorption and anti-evaporation is completely different from those in conventional ways. An extensive experimental simulation and commercial test were carried out and the results show that the suppressor can meet the requirement of roadway dust suppression in an open pit and other similar sites because of its excellent dust suppression effects such as adhesion, agglomeration, moisture absorption and anti-evaporation and pave-concretion, and self-adaptive to natural environment, simple preparation technology, rational comprehensive cost and high specific performance.
