UNDERGROUND LOAD & HAUL
Reluctance (SR) drive to capture and reuse braking energy while also
equipped with KESS (Kinetic Energy Storage System).
The 22HD also has a simple control suite allowing the operator to
concentrate on maximising productivity. Automated control functions allow
operator to perform complex operations at a button press while its “heavy-
duty design means less failures and more uptime.” The bucket design
allows easy filling and low wear and a central auto lubrication system
minimises scheduled service activity and protects critical structural linkages
and joints. The hydraulic system with piston pumps mean cooler operation
and longer life.
At Prominent Hill underground, the operations delivered 680,000 t of ore
in Q1 2018 at 1.81% copper, representing consistent quarter on quarter
production. The third decline construction has progressed, with final portal
position selection complete and break through expected in Q2. The fourth
haulage decline into the lower open pit will commence in Q2 and
completion is expected in Q3. Procurement activity for the crusher feed and
underground ore rehandle contract is underway with contract execution
expected in Q2. The combination of new access declines into the
underground and utilisation of the rehandle fleet will lift underground ore
production in H2 to facilitate full year guidance of 2.8-3.1 Mt.
Small and low profile updates
Ontario is investing in innovative new technology projects in Northern
Ontario that will help improve mine productivity, increase operating
efficiencies, and help northern businesses expand their global market
reach. Michael Gravelle, Minister of Northern Development and Mines,
made the announcement while speaking about the province’s thriving
mining industry during the official opening of the Ontario Pavilion at the
PDAC in Toronto.
Funding through the province’s Northern Ontario Heritage Fund
Corporation (NOHFC) will support the following four mining supply and
service companies in the districts of Greater Sudbury and Nipissing.
RDH Mining Equipment Ltd will receive over C$200,000 to create a very
small LHD machine. This one-cubic-metre Load Haul Dump machine the
company hopes will open up the narrow-vein market for RDH and serve as a
frame design for future powertrain development. Earlier this year, SMT
Scharf AG indirectly acquired an interest in 100% of the shares in RDH,
based in Alban, Canada, through its wholly-owned subsidiary SMT Scharf
Corporation. With this acquisition, SMT Scharf AG is further pursuing its
corporate strategy and strengthening its market position as an integrated
system provider in the underground logistics area.
AARD Mining Equipment has delivered the first mobile mechanised
equipment to Ivanhoe Mines' Platreef project in South Africa, a 5.5 t class
LP LHD for off-shaft development work on the 750, 850 and 950 m levels.
In order to meet increasing demand in the mining industry and offer
customers top-quality products with the best price-performance ratio,
Providing full service mining
solutions and innovation around
the world for over 55 years.
