NARROW VEIN & LOW PROFILE MINING Resemin, since launch last year, has sold three MUKI Bolters to local South America customers And the company recently developed the Small Bolter 99 MESHA, a roof bolter intended to mechanise and install MINAX mesh from Geobrugg. Valenzuela said: “This kind of mesh is high resistance and specially recommended for rock bursts and seismic events.” Resemin is also making advances when it comes to both automation and electrification. Last year, the company sold two MUKI LHBP- 2R long hole drilling machines to Australia, on top of three units this year to India, equipped with CAN BUS system for tethered tele-remote control. And, as reported in the battery-electric equipment article in February, the company is looking to electrify its fleet. Resemin plans to launch, in October 2019, its first battery-powered single boom front face Troidon 55 machine, Valenzuela said. “After the trial of this machine (a medium size rig), we will offer our entire fleet of drilling rigs with a battery-powered system,” he said, clarifying the battery will be employed for tramming, with drilling operation via tethered connection to the mine, which, at the same time, recharges the battery. Paus profile “Compact, manoeuvrable vehicles that are safe and have an excellent total cost of ownership” – this is the focus of product development and production for narrow vein mining vehicles at Paus. The Germany-based company’s equipment range covers several parts of the narrow vein mining process. For example, after blasting, the Paus Scaler 853 S8 comes in and secures the drift. Then, if conveyor belts or trains are not used to transport the rock to the chute, the Paus PMKM dump trucks can provide safe passage. The Paus-Fahr-Lader PFL LHD, meanwhile, is available in two versions for narrow vein mining: the PFL 8 with 0.8 m³ bucket, or the PFL 10 with 1 m³ bucket. The Universa 40 vehicles from Paus are available for the further expansion of the drift with the necessary infrastructure such as air- 42 International Mining | JULY 2019 this scaler class,” the company said. All functions are available in different modes, with the operation more intuitive and the training time immensely reduced. “For the ‘hard’ work, Paus has equipped the Scaler 853 S8 with a powerful NPK hammer,” the company said, explaining that continuous tool lubrication reduces the contamination of the hydraulic oil – “not only can the hydraulic oil be used for longer, wear is also noticeably reduced”. ROPS/FOPS-certified operator-protecting roof and a robust protective grill provide effective protection when scaling at heights of 8-10 m, Paus said. ducting system, lighting, power lines, etc. The Universa 40 is designed by Paus as a “platform vehicle” and can therefore be configured for the most diverse requirements, according to the company. “Equipped as a workshop vehicle, tools can be transported quickly and safely, or configured as a manoeuvrable passenger transporter; engineers, mine surveyors, foremen and geologists are driven to their workplaces,” Paus said. Paus has equipped the “The design focuses on: Scaler 853 S8 with a powerful NPK hammer reducing attrition and increasing service friendliness. The facts: With Paus ‘Power Flow’, the variable adjustment pumps ensure that the oil supply is regulated as required.” The advantages are fuel savings, lower oil temperatures and, thus, reduced ageing of the components. Optimised hydraulic lines and the use of as few hosepipes as possible simplify maintenance. In addition, hose breakages are avoided. Standard features such as a hydrostatic drive, a ROPS/FOPS-certified driver's cab, safety brake and spacious comfort cab “prove safety goes well with comfort”, the company said. Paus also highlighted the “fatigue-free, ergonomic working” that comes with using its Scaler 853 S8. “The spacious cab, with comfortable driver's seat and functionally arranged instrument cockpit, offers one of the best all-round views in “The combination of articulated steering (±40°) and swivelling boom (±45°) ensures unmatched manoeuvrability of the scaler types 853 S8 and 1253 S10,” the company concluded. DOK-ING makes NRE progress In this same feature last year, DOK-ING provided an overview of the company’s extra low profile dozers, which have been gaining in prominence in the South Africa platinum and gold mining space. Building on its expertise providing both diesel and electric versions of these low profile machines, the company started manufacturing electric narrow reef equipment (NRE) in March 2018. The process for NRE dozers, drill rigs and support rigs was completed earlier this year, with only the support rig still requiring testing in a One of the unique features of DOK-ING’s NRE equipment includes the ability to work in stoping widths from 0.9-1.7 m
