Jinggong coal mining involves a series of complex operations that transition from the surface to underground environments. As an underground operation, the production process faces more challenging natural conditions. The main characteristics of coal mining include the necessity for mine ventilation, and it is also prone to five major hazards: gas, coal dust, roof falls, fires, and water inrushes. 1. Mine Ventilation. Since coal mining takes place underground, the air from the surface can mix with harmful gases and dust as it travels through the tunnels and work areas. Additionally, factors such as geothermal heat, human activity, and mechanical operations contribute to increased temperature and humidity underground. This creates uncomfortable working conditions, making proper ventilation essential for maintaining a safe and healthy environment for miners. 2. Gas and Dust Hazards. During the extraction process, gas and coal dust are inevitably generated. Under certain conditions, these substances can lead to explosions, resulting in serious injuries or even fatalities, along with significant property damage. Moreover, prolonged exposure to coal dust can cause respiratory diseases such as pneumoconiosis, which severely affects miners' health and quality of life. 3. Roof Falls. In underground mining, the weight of the overlying rock can cause the roof to collapse if not properly managed. Poor planning or failure to reinforce the roof can lead to dangerous accidents, posing a direct threat to the safety of workers. 4. Mine Fires. Fire is another critical hazard in coal mining operations. Once a fire breaks out, it can result in the loss of valuable coal reserves, disrupt normal mining activities, and often trigger secondary explosions involving gas and coal dust, thereby increasing the scale and severity of the disaster. 5. Water Inrush. Throughout the construction and operation of a mine, surface water and groundwater may seep into the underground workings through various pathways. To prevent this, mines implement numerous preventive and drainage measures. However, if the inflow of water exceeds the capacity of the drainage system or if old water-filled areas or karst water are accidentally encountered during mining, it can lead to flooding, causing serious damage and operational disruptions.

Kemei designs, tests, and builds all types
of grinding wheels. The aim of abrasive grinding wheels is to modify the surface structure
and/or preparation of a workpiece. In general, fixed abrasive wheels are
characterized by grit size (abrasive grain), bonding type, substances used, and
the grade and structure of the fine grinding wheel. Users of our wheels can
choose between a specially formulated wheel tailored to their exact needs, or
choose one of our reliable standard specifications. Additionally, the
physical and chemical properties of the diamond and/or CBN crystals can
influence the performance of the grinding wheel. Having over 20 years of
experience in our field has earned us the prestige of manufacturing the highest
quality fixed super abrasive wheels and abrasive grinding wheels. Above all,
being an abrasive wheel manufacturer, allows us to offer you success in your
future projects.
Kemei produce and aim on the following
types grinding tools, such as aluminum oxide grinding wheel, silicon carbide
grinding wheels, mounted points, Diamond Grinding Wheels, CBN Grinding Wheels
and all types of saw blades and cut off wheels.
If you need any type of grinding tool or
professional advice about grinding on your workpieces. Don`t hesitate to
contact us!
