In what fields can carbon dioxide gas rock blasting technology be applied?
Product Link：
Mining field:
Open-pit mining: In open-pit mines, it can be used for rock crushing, ore body separation and other operations. Its advantage is that it can reduce damage to the surrounding environment, reduce blasting vibration and flying rocks, and avoid the safety hazards caused by traditional explosives blasting, and ensure the life safety of mine workers. For example, some large open-pit limestone mines, iron mines, etc. have begun to use carbon dioxide gas blasting technology for mining operations.
Mine excavation and recovery: In underground operations, carbon dioxide gas blasting will not produce open flames and explosive gases, which is safer for mines with flammable and explosive gases such as gas. It can be used for tunnel excavation, coal dropping on the working face, and handling coal seam faults, which improves the production efficiency of mines.
Ore mining and selection: It helps to crush ores and extract valuable substances from ores, and can improve the efficiency and quality of mineral processing to a certain extent.
Engineering construction field:
Tunnel and subway engineering: In the construction of tunnels and subways, hard rock formations are often encountered. Carbon dioxide gas blasting technology can crush and excavate rocks without affecting surrounding buildings and underground pipelines, providing convenience for the construction of tunnels and subways. For example, in the construction of subways in the central area of the city, the use of this technology can reduce the impact on surrounding residents and buildings.
Municipal engineering: It can be used for widening urban roads, excavating underground pipe trenches, and demolishing buildings. Compared with traditional blasting methods, carbon dioxide gas blasting produces less noise and dust, and has less pollution to the urban environment, which meets the environmental protection requirements of urban construction.
Water conservancy and hydropower engineering: In the construction of water conservancy and hydropower projects such as dams and hydropower stations, it can be used for excavation of rock foundations, slope treatment and other operations. Its safety and environmental protection characteristics can meet the high requirements of water conservancy and hydropower projects for construction safety and environmental protection.
Emergency rescue field:
Road clearance: After natural disasters such as earthquakes and landslides, roads may be blocked. Carbon dioxide gas blasting technology can quickly break obstacles, clear roads, and provide channels for the transportation of rescue personnel and materials.
Treatment of barrier lake: To remove the danger of barrier lake, it is necessary to clear the rocks and earthworks that block the river. Carbon dioxide gas blasting technology can blast the barrier without causing secondary disasters, lower the water level of the barrier lake, and eliminate safety hazards.
Industrial production field:
Cement, steel, electricity and other industries: It can be used for clearing the blockage of equipment and facilities such as preheaters, rotary kilns, and furnace slag, as well as the agglomeration treatment of garbage incinerators in urban thermal power plants. It can quickly and effectively solve the problem of equipment blockage without affecting the normal operation of production equipment, and improve production efficiency.
Stone mining: Carbon dioxide gas blasting technology can achieve directional blasting of stone, will not crush rocks, and make the size of stone controllable, which is suitable for mining large-sized stone and precious stone.
