Aker Wirth raise boring machines and cutters have been in operation in the hardest rock, up to 700MPa USC. The equipment ranges from 112kW to 600kW installed power, the cutting diameters from 1m to 6m and the boring depths up to 1,300m. Aker Wirth built the world’s largest raise borer, the HG 380 with an operating torque of max. 710kNm.
Apr 01, 2017 Part of the ore is mined by electric shovels that load into trucks, which deliver it to a raise driven from an underground level to the bottom of the pit. The rest is mined by two tower excavators using 3-yard drag buckets, which will operate within a maximum clean-up radius of 700 feet, the average digging radius being 170 feet.

Sep 21, 2020 The Rhino is manufactured by TRB-Raise Borers in Finland but is equipped with Sandvik tools and is distributed by Sandvik. It is a fully mechanised and self-contained electro-hydraulic mobile raiseborer designed for slot raising in underground mining. The latest models also have an optional back reaming module.
The unit was specifically developed to meet industry requests for a 1.06-m-diameter box hole boring machine that would meet all Australian mine safety standards, plus be low profile, and could also be quickly switched to operate as a conventional raise borer, capable of pulling up to 3-m-diameter holes.
Mar 27, 2019 Having encountered this demand for versatility, in 2014, TRB-Raise Borers created the Rhino 100, a new type of highly mobile, self-contained raise borer for underground production drilling. Mounted on rubber wheels, operated by one operator, and with a setup and demob time of 15 minutes, the Rhino is an efficient tool for raise boring and slot ...
Jan 07, 2020 Mobilaris Mining Intelligence makes mining more efficient by tracking equipment in real time. At the 777 zinc-copper mine in northern Canada, the new Epiroc technology is boosting Hudbay’s mucking rate. The 777 zinc-copper mine in Flin Flon, Manitoba is on the wane. After 15 years in production, the underground operation is expected to close in 2022 unless Hudbay Minerals discovers more ore.
The two men work underground until they have an accumulation of ore and then they usually get assistance to raise it. The men then dress the ore themselves and prepare it for the market”. “It is these small ventures that are the worst ventilated, where perhaps 4 or 6 men are working on their own.

Raises up to 6 m in diameter and up to 1000 m in length are not uncommon. The raise-boring method is used to produce ventilation shafts, ore passes, manways, penstocks etc. Blind boring When a raise is required but there is no access to the upper level, it has to be bored blind from below, usually without a pre-drilled pilot hole.
Raise boring is the process of boring a raise. A pilot hole is drilled from the drill rig to an underground cubby or tunnel. A reamer head with cutters is then attached to the drill string. The drilling rig at the surface or upper level then pulls tension onto the drill string while rotating, causing the large diameter cutting bit to cut a large hole from the underground tunnel or level to the surface or upper level.
Mar 24, 2020 Created by raise boring machines, these wide-diameter holes provide void spaces in the stope into which blasted ore can expand, improving fragmentation.
Mar 25, 2020 The arrival of the Rhino 100 mobile raise borer has proved a game changer for underground contractor Raising Australia, part of the Byrnecut Group. Since introducing its first Rhino in 2017, the company has been able to slash slot-raise production times, improve productivity for its customers, and significantly increase its own revenue.
