Epiroc is showcasing the latest additions to its rock reinforcement line at MINExpo 2021 in Las Vegas, with the new Boltec M10 and Boltec E10.
The Boltec M10 (pictured) and the larger Boltec E10 are fully mechanised rock bolting rigs for medium- and large-sized tunnels, designed to increase productivity and bolt installation quality thanks to intelligent options and compatibility with different bolt types, according to the company.
Peter Bray, Global Product Manager, Rock Reinforcement Equipment with Epiroc’s Underground division, said: “As mining operations move ever deeper underground, the difficulty in bolting and securing increasingly fragmented rock is rising. The Boltec M10 and Boltec E10 introduce previously unavailable autonomous functionality: this is the benchmark in underground rock reinforcement.”
With self-drilling anchor bolts (SDA) in combination with pumpable resin, the Boltec M10 and Boltec E10 can perform single bolt and multi-bolt installation automatically, according to Epiroc. These new functions work hand-in-hand with teleremote bolting and offer bolting potential during shift changes or other situations where off-board control during bolting is needed, the company says.
With in-built flexibility, the Boltec M10 and E10 have the ability to handle several different types of bolts, mesh and installation methods as well as radial, face bolting and extension drilling capability, Epiroc says. The boom bolter concept ensures the operator stays at a safe distance from the working area of the machine during the bolting process.
The new Boltec rigs come with an optional battery-electric driveline, which brings additional advancements for operator health, maintenance, ventilation and cooling.
The Boltec M10 and Boltec E10 also come with a completely redesigned operator station. The optional ROPS- and FOPS-certified cabin sets new standards for operator safety and comfort thanks to significantly reduced noise levels down to only (65 dB(A)), HEPA air filtration and better visibility, according to Epiroc. The air-conditioning system also features automatic temperature adjustment, further boosting operator comfort.
