Mine pneumatic fire-prevention and extinguishing grouting device
The ZHJQ series mine-use pneumatic grouting and fire-extinguishing device is a new type of grouting equipment. Its two mixing tanks enable the alternating supply of two chemical solutions, with continuously adjustable flow rates and precise mixing ratios. It can be configured to deliver filling and sealing materials—including mine-grade gels, slurries, backfilling and sealing agents, and fire-retardant plugging agents—as well as dust-suppression and inerting materials, which are then pressurized and conveyed through pipelines to the fire-extinguishing site.

The mine pneumatic grouting pump is a highly efficient grouting device specially designed for coal mines and other underground mining environments. Powered by compressed air, this equipment utilizes pneumatic technology to ensure stable delivery of high-viscosity slurries. Thanks to the large-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 piece of equipment for mine support and grouting reinforcement operations.

Mining hydraulic grouting pump
The 2ZBYSB series variable hydraulic grouting pump is a high-performance grouting pump featuring a dual-cylinder, single-action reciprocating piston mechanism, powered by an explosion-proof motor. It is a fully hydraulic, pressure-adjustable grouting pump designed to deliver precise injections of materials—such as quick-setting substances or mixtures like water, cement slurry, and water glass—into fractures and cavities within rock formations or soil. This process effectively reduces water seepage while simultaneously consolidating rock layers and stabilizing the ground.

The 3NBB series mining electric mud pump is a horizontal, three-cylinder, single-acting reciprocating piston pump. This pump can be used as auxiliary equipment for drilling rigs, delivering flushing fluid into the borehole during core drilling operations, circulating it within the hole to keep the bottom clean while simultaneously cooling and lubricating the drill bit and drilling tools. It also helps stabilize the borehole walls, preventing collapse. Additionally, it can serve as a cement slurry injection pump in foundation treatment projects, capable of conveying cement slurry, yellow mud slurry, fly ash slurry, coal slime, and more. Furthermore, it is ideal for use in coal mines to deliver slurry during measures aimed at preventing spontaneous combustion and reinforcing fractured coal and rock strata.
