Pneumatic Grouting Pump for Mining
The pneumatic grouting pump for mining is a high-efficiency grouting device specially designed for coal mines and other underground mining environments. This equipment uses compressed air as the power source and employs pneumatic technology to achieve stable delivery of high-viscosity slurry. Due to the large effective area ratio between the cylinder and the grouting cylinder, it can generate high grouting pressure even under relatively low air pressure conditions, making it an indispensable key device in mine support and grouting reinforcement operations.

Pneumatic Grouting Pump
"Coal Mine Safety Regulations"
Article 45 When using the freezing method to excavate shaft wells, the following provisions shall be observed:
- The shaft wall structure of the frozen shaft shall adopt double-layer or composite shaft walls. After the construction of the frozen shaft section is completed, grouting between the walls shall be carried out in a timely manner. During grouting, the temperature of the concrete in the inter-wall layer shall not be lower than 4°C, and the frozen wall must remain sealed and able to withstand external hydrostatic pressure.
Article 51 When the shaft passes through water-bearing rock formations or fractured zones with a predicted water inflow greater than 10m3/h, surface or working face pre-grouting methods shall be used for water blocking or reinforcement. Before grouting, grouting engineering design and construction organization design must be prepared.
Article 107 For coal mining faces using the artificial roof layered caving method, the artificial roof must be laid intact and tightly overlapped.
When using the layered caving method for mining, grouting or water injection must be carried out into the goaf. The specific requirements for grouting or water injection shall be clearly specified in the operating procedures.
The mine-use pneumatic grouting pump is a high-efficiency grouting device specially designed for coal mines and other underground mining environments. This equipment uses compressed air as the power source and pneumatic technology to achieve stable delivery of high-viscosity slurry. Due to the large effective area ratio between the cylinder and the grouting cylinder, it can generate high grouting pressure even under low air pressure conditions, making it an indispensable key device in mine support and grouting reinforcement operations.
The pneumatic grouting pump can be used with a matching mixing bucket to achieve continuous stirring and delivery of slurry, improving the uniformity and efficiency of the grouting process.
This series of pumps comes in various specifications to meet different grouting needs, effectively coping with various complex geological environments, ensuring the stability and uniformity of grouting operations.
Product Uses
Mainly used in mine operations, tunnel construction, hydraulic engineering, subway construction, building engineering, bridge construction, highway and railway subgrade maintenance, and flood control and emergency rescue, for grouting water blocking, filling voids, grouting consolidation of fractured rock formations, and anchor support.
Product Features
- Uses compressed air as the power source, reliable in use, and can be used in flammable, explosive, wet, and dusty working environments;
- Due to pneumatic transmission, the pump's grouting performance is very suitable for conditions requiring high flow at low grouting pressure and low flow at high grouting pressure;
- High work efficiency and comprehensive functions, supporting injection of single-component slurry as well as dual-component slurry; capable of injecting chemical slurry as well as cement and other types of slurry.
- Low energy consumption, low vibration, low noise, high efficiency, stable and reliable performance, easy pressure and flow adjustment, and long service life.
- Can inject Marisand, Rockshield, yellow mud slurry, fly ash, polymer colloidal fire prevention and extinguishing materials, etc.
- Can perform fire extinguishing with single-liquid A, dual-liquid AB, or triple-liquid ABC mixed fire prevention and extinguishing materials.
