Choosing the right equipment for underground shotcrete is essential for efficient concrete placement in mining, tunneling, and underground construction projects. Restricted access, low ceiling heights, and long material delivery distances can make underground concrete applications challenging. Specialized mixing and pumping equipment helps contractors handle compatible materials when ready-mix concrete is not a practical option.
The Blastcrete MineMate is a labor-saving concrete mixing and pumping system designed for underground mine sealing, grouting, and underground shotcrete applications. It combines an X-10 ultra-high-pressure swing tube piston pump with a high-shear continuous mixer to provide an integrated solution for preparing and pumping compatible concrete materials.
With an output capacity of up to 12 cubic yards per hour and the ability to pump suitable materials over distances exceeding 500 feet, the MineMate supports demanding underground operations. Its low-profile design and integrated material screw conveyor also help streamline material handling in selected confined work areas.
What Is Equipment for Underground Shotcrete?
Equipment for underground shotcrete includes machinery used to prepare, pump, and apply concrete mixtures to underground surfaces. These systems can support tunnel construction, ground support, mine rehabilitation, and other underground concrete placement applications.
The right equipment depends on the shotcrete mix design, aggregate size, required output, pumping distance, application method, and site conditions.
The Blastcrete MineMate combines continuous mixing and high-pressure pumping in one machine. It is designed for underground shotcrete, mine sealing, and grouting applications where ready-mix concrete is unavailable or impractical.
For contractors seeking a compact underground concrete mixing and pumping solution, the MineMate offers an integrated system for compatible materials.
Blastcrete MineMate: Integrated Mixing and Pumping Technology
The Blastcrete MineMate combines material preparation and pumping functions to help streamline underground construction operations.
1. Ultra-High-Pressure Swing Tube Piston Pump
The MineMate features a 3-inch × 24-inch ultra-high-pressure swing tube piston pump designed for demanding concrete pumping applications.
With pumping pressure of up to 2,200 PSI, the system provides the pressure capability required for compatible materials and suitable delivery-line configurations. Actual pumping performance depends on material characteristics and operating conditions.
2. High-Shear Continuous Mixer
The integrated high-shear continuous mixer prepares material for pumping as part of a combined mixing and delivery process. This arrangement can simplify equipment coordination and support an efficient workflow on underground projects.
3. Low-Profile Design for Underground Work Areas
Underground mines and tunnels often have restricted ceiling heights and limited equipment access. The MineMate is designed to operate within a 6-foot ceiling, making it suitable for selected low-clearance environments.
Its compact configuration helps contractors position the machine in confined work areas, subject to site access and operating requirements.
4. Integrated Material Screw Conveyor
The MineMate includes a material screw conveyor with a bin indicator to charge the continuous mixer. This feature helps streamline material feeding and reduces the need for manual charging.
5. Extended Pumping Distance
The MineMate can pump suitable materials over distances exceeding 500 feet. This capability provides flexibility when the equipment must be positioned away from the underground placement area.
Actual pumping distance depends on material properties, mix design, delivery-line configuration, elevation changes, and site conditions.
