The 3rd (2020) National Green Mining Development Conference with the theme of "Standard Leading and Green Empowerment" was held recently in Chengdu. As a professional member of the Green Mine Industry Alliance, Bluestar Chonfar was invited to attend the conference. Its "Key Technologies and Equipment for Dust Prevention in Fully Mechanized Mining Face" project won the second prize in the 2019 Green Mine Science and Technology Award for Technology Research and Development.

At the Green Mine Technology Development Forum of the conference, the representative of Bluestar Chonfar presented a special report on New Progress of New Technologies for Energy Saving and Optimization of Mine Ventilation System, introducing in detail the latest research results and related patented technologies of the company in the design of mine ventilation system, optimization method theory, ventilation system "on-demand control" and other aspects. As the main compilation unit of the Interpretation of Green Mine Construction Standards?in the chemical industry, representatives of Bluestar Chonfar also introduced policy documents and relevant specifications of green mines in the chemical industry.

At the same time, the award ceremony of the 2019 Green Mine Science and Technology Award was held. The project of ?"Key Technologies and Equipment for Dust Prevention in Fully Mechanized Mining Face" participated by Bluestar Chonfar won the second prize in the Green Mine Science and Technology Award for Technology Research and Development. The project is focused on the research of the dust diffusion law, dust wetting property, atomization performance of the nozzle, spray dust reduction mechanism, ?high-efficiency spray technology and equipment, etc., provides theoretical and technical support for the mine dust removal and green mine construction to improving the production and working environment of miners, protecting the health of workers, reducing the incidence, morbidity and mortality of pneumoconiosis, and effectively reducing the national expenses for medical treatment and death pension for pneumoconiosis workers.

The National Green Mining Development Conference, held once a year, has become an important platform for publicizing green mine policies, exchanging experiences in green mine construction and promoting cooperation in green mines. The Conference was jointly sponsored by Zhongguancun Green Mine Industry Alliance, Green Mine Ecological Restoration Professional Committee of International Production and Economic Association, and Southwest University of Science and Technology, etc.
