MacLean Engineering

Ground Support

MacLean Engineering designs, manufactures and markets engineered solutions across the mining, municipal, environmental and industrial goods sectors.

The use of mobile, concrete mixers for sprayed concrete in underground mines requires reliable equipment to ensure the final product is of high quality and is applied in an efficient manner. The Mine-Mate™ TM2 & TM3 Transmixers are an integral part of the wet shotcrete process, providing high capacity, high speed transport of shotcrete/concrete in a fit-for-purpose package, while the AG3 is the choice for turning dry-mix into wet or for adding additional mix components such as fibers, another example of MacLean designing and manufacturing hard rock mining equipment built for life underground.

The Mine-Mate™ SS-2 and SS-3 Shotcrete Sprayers are rugged mechanized shotcrete spraying systems, developed specifically for underground ground support applications. The unit is optimized to make use of the latest developments in wet shotcrete materials, additives and spraying processes for reduced airborne particulates while ensuring high quality performance.

Efficient scaling of loose rock from mine walls, backs and faces is of prime importance for underground production safety and productivity. The MacLean mobile RS3 Scaler is the latest addition to the MacLean ground support fleet. Combining MacLean quality, ruggedness and performance with industry-leading ergonomics and all-round operator visibility, the RS3 Scaler is the unit for reliable ground control.

Designed to supplement our suite of ground support solutions, the UBM Utility Bolter delivers height and reach options on a wide range of ground support and mine services functions.  Like the MacLean 900 Series and SSB Small Section bolters, the UBM is purpose built with safety and quality of installation in mind.

The MacLean CB3 is a one-stop, mechanized solution for cable bolt insertion and grouting. With the CB3, operators no longer have to endure the strain and fatigue of repetitively pushing cable lengths by hand – the integrated boom basket, cable feed mechanism, and grout pump design delivers productivity, safety and ergonomics for all hard rock cable bolting needs.

Based upon the highly successful MacLean Series 900 Scissor Bolter, the SSB Small Section Bolter is the ground support solution for smaller mine openings. The benefits of safety, productivity, versatility and quality of installation again combine to provide the ideal tool for the mine development cycle and rehabilitation operations.

The MacLean Series 900 Bolters, the 928 (eight foot-wide deck) and the 946 (seven foot-wide deck) provide a complete ground support system for underground hard rock mines. The benefits of safety, productivity, versatility and quality of installation combine to provide the ideal tool for the mine development cycle and rehabilitation operations.

The 975 Omnia Bolter delivers a cutting-edge ground support solution for almost any application context. Gen-3 drill feeds with high-durability wear guides, a single-bolt bolt handler, and an increased 3,000 lb. deck payload can now be combined with a wide range of options that provide customers with the utmost in flexibility to match the unit with their specific ground conditions and mining method. Battery power, high-reach, resin injection, and/or a seven foot-wide deck configuration all position the 975 Omnia to offer the signature MacLean safety, durability and productivity in response to varying and evolving ground support requirements and operational business drivers across the global hard rock industry.
