Prior to the commencement of operations in its new mining zone, the enterprise sought to prevent the recurrence of dust issues encountered in its legacy mining area. To this end, it invited Professor Ren, Chairman of our company, to conduct a technical review. During the review, Professor Ren participated in a joint expert evaluation alongside specialists from five countries, including the United States, Australia and Chile. He proposed exceptional solutions, particularly in the domains of dust suppression and ventilation system design. In recognition of his expertise, the enterprise’s subsidiary mining company has extended a subsequent invitation for Professor Ren to conduct an on-site inspection and develop a more comprehensive and detailed solution.
