The purpose of TGMS system is based on the fact that a large amount of dust is generated during the production processes of drilling, blasting, truck loading and unloading, primary and secondary crushing, shovel loading, and truck transportation in open-pit mining sites; Moreover, it has the problems of multiple dust producing points, high dust production, and high dust concentration in the air; In addition, the open-pit mining dust also has the characteristics of high dispersion and is developed into an intelligent comprehensive management system. By combining dry and wet methods, targeted dust suppression control is carried out for each ash discharge point to solve problems at the source. Due to the fact that the entire mining production is in a dynamic process, all control and management of dust removal are also synchronously monitored based on TMAS system, thus achieving low energy consumption and low cost dust removal effects.
