Efficient concrete pumping for underground construction is essential for mining, tunneling, underground rehabilitation, and specialized concrete placement projects. Limited access, restricted ceiling heights, and long material delivery distances can make underground concrete placement challenging. Choosing the right mixing and pumping equipment helps contractors manage these conditions when ready-mix concrete is unavailable or impractical.
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, providing 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 construction operations. Its low-profile design and integrated material screw conveyor also help streamline material handling in selected confined work areas.
What Is Concrete Pumping for Underground Construction?
Concrete pumping for underground construction involves transporting concrete or compatible cementitious materials through a delivery line to designated underground placement areas. This process can support mine sealing, grouting, shotcrete applications, and other specialized construction activities.
Underground projects often require equipment that can operate within restricted spaces while delivering material over considerable distances. The appropriate system depends on the mix design, required output, pumping distance, access limitations, and project specifications.
The Blastcrete MineMate combines continuous mixing and high-pressure pumping in one machine. This integrated configuration is designed for underground applications where ready-mix concrete is not a practical option.
Blastcrete MineMate: An Integrated Underground Concrete Pumping System
The Blastcrete MineMate combines material preparation and pumping functions to help streamline underground concrete placement 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 needed for compatible materials and suitable delivery-line configurations. This supports material delivery to designated underground work areas.
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 a more efficient workflow on underground construction projects.
3. Low-Profile Design for Restricted Spaces
Underground mines and construction sites frequently have limited ceiling heights and restricted access. The MineMate is designed to operate within a 6-foot ceiling, making it suitable for selected low-clearance environments.
Its compact design helps contractors position the equipment in confined work areas, subject to site access and operating requirements.
4. Integrated Material Screw Conveyor
The MineMate features a material screw conveyor with a bin indicator for charging the continuous mixer. This system 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 gives contractors flexibility when the equipment must be positioned away from the concrete placement area.
Actual pumping performance depends on material properties, mix design, delivery-line configuration, elevation changes, and site conditions.
