Apply many new technologies
According to Decision No. 55/QD-TTg of the Prime Minister approving the Vietnam Coal Industry Development Strategy to 2030, with a vision to 2045, the coal industry continues to maximize its internal resources combined with expansion. international cooperation to research, deploy and apply scientific and technical advances and modern new technologies, especially the achievements of the 4th industrial revolution in the management of exploration, exploitation, screening, processing, transporting and using coal.
The coal industry has promoted the application of science and technology in production
Besides, improving the protection and improvement of the ecological environment, promoting cleaner production and moving towards a circular economy, adapting to climate change, reducing greenhouse gas emissions and complying with commitments. international organizations that Vietnam participates in.
In recent times, coal factories and mines have continuously promoted investment, innovated and applied technical advances, and applied high-tech science and technology to the exploitation and processing of finished coal products. Along with that, we actively manufacture and localize many equipment and components to serve production and exploitation.
The coal industry also focuses on mechanization and automation at all stages, considering this a key task to improve productivity, mining output and ensure labor safety, limiting negative impacts. harmful to the natural environment.
According to the Department of Science and Technology, Ministry of Industry and Trade, in the field of mineral exploitation and processing, research and investment in technological innovation have contributed to increasing coal output across the industry by an average of 9.4%/year. .
In underground mining, the level of mechanization and modernization is enhanced through the application of new technologies such as: Using advanced anti-frame racks, chain racks, self-propelled outriggers; Coal cutting by cutting machine, planing machine; Excavation using self-propelled drilling machines combined with loaders, combined excavators, various types of reinforced concrete anchors, shotcrete concrete, plastic anchors, cable anchors in digging and supporting the tunnel.
In addition, the technology of exploiting and properly sorting Titan-Zircon placer ore in the red sand layer has been applied to production practices at a number of companies exploiting and processing titanium placer ore in Binh Thuan region; Graphite ore sorting and deep processing technology at Bao Ha mine, Lao Cai has created a new source of raw materials capable of replacing imported goods, contributing to proactively sourcing raw materials and reducing product costs for the production of some domestic industry.
Or, the technology to produce 99.99% tin by electrolytic refining method with diaphragm has been successfully applied at Thai Nguyen Metallurgical Mine Co., Ltd.; Technology for processing soluble minerals in Phu Tho area as raw materials for the ceramic, paint, pharmaceutical and cosmetic industries; Technology for selecting and converting sericite ore as raw material for the paint and polymer industry applied to mines in Huong Son – Ha Tinh region.
Technology for salvage extraction of useful elements in the process of selecting and refining Sin Quyen copper ore applied at Sin Quyen copper flotation plant – Lao Cai and Tang Loong copper smelting plant – Lao Cai; Apatite ore screening and processing technology helps ensure and stabilize the quality of type III apatite ore concentrate to meet the needs of providing stable quality raw materials for DAP production plants applied at the Group’s apatite ore processing plant. Vietnam Chemical Group.
Improve productivity, quality, reduce product costs
According to the assessment of the Ministry of Science and Technology, in the field of mineral exploitation and processing, science and technology activities have contributed to promoting technological innovation, improving productivity, quality, and reducing product costs. products, creating new products to replace imports in key economic sectors. The rate of mechanization in underground mining has increased dramatically from 10% to 80% in recent years.
By 2030, the Government requires the mineral exploitation and processing industry to use advanced technology and equipment.
Typical examples include successfully manufacturing equipment, well digging construction technology and vertical well loading shafts applied to the Nui Beo underground coal mine. This is the result of implementing a science and technology project chaired by the Vietnam Coal and Mineral Industry Group (TKV), which has contributed to improving the technical capacity of the team of researchers, engineers, workers in mastering issues from the design stage, establishing technological processes, manufacturing equipment and constructing deep mine mining projects; Improve domestic manufacturing capacity of vertical well loading shaft system equipment.
At the same time, contributing to gradually replacing imported goods, developing domestic mechanical production, saving foreign currency, creating initiative and speeding up the implementation of projects, allowing to reduce product costs. , reducing coal production costs, contributing to the sustainable development of the coal industry.
From the achieved results being applied at Nui Beo coal mine, units in TKV are continuing to design the Khe Cham II-IV underground mine project, verifying
