Advanced Engineering Group’s Poly Sheet liners provide strong resistance to abrasion and impact wear in raw materials handling.
The resilient polyurethane lining sheets also help to reduce noise and will not corrode.
They are six times lighter than steel, making them easy to handle and install, and are available in various Shore hardnesses and thicknesses.
The liners are relatively flexible and can be installed on both flat and slightly curved surfaces.
For additional rigidity, an optional, unique textured resin-composite backing plate can be fitted to the liner. The backing plate prevents fine material ingress behind the liner – which could cause lifting – while also aiding with fixing.

BHP will be looking at the prospect of trialling automated haul trucks at the Mount Arthur coal mine, a decision that will be finalised in the next 12 months.

If implemented, this would be the first trial of autonomous mining haul trucks in NSW, which was flagged by BHP coal boss Dean Dalla Vale early this year.

BHP has already been testing driverless haul trucks at their Jimblebar iron ore mine in Western Australia for more than 12 months, and will soon ramp up the fleet from nine to 12 trucks.

A BHP spokesperson told Australian Mining Mt Arthur is on the cusp of beginning an identification study into the requirements of such a trial, such as examining potential suppliers, equipment, and equipment modifications to suit the mine.

The identification study will be completed by the end of FY15, after which BHP Mt Arthur will determine whether to proceed with the trial.

“If a decision is made to go forward with a field trial, the autonomous truck project would be conducted by a dedicated project team in an area of the mine pit separate from main operations,” the spokesperson said.

“No decision has been made, but we will continue to keep our employees updated.”

The Planning and Assessment Commission recently approved an extension of the Mt Arthur coal mine operations until 2026, on the grounds that it would facilitate employment of up to 2600 workers, Newcastle Herald reported.

NSW member of the legislative council for the Greens Jeremy Buckingham said the prospect of a new trial indicated “the absolute hypocrisy of these multinational coal companies”.

“They use the spectre of job losses to demand mining approvals, while at the same time act to implement measures that cut employment,” Buckingham said.

Last week Mt Arthur announced 150 jobs at the mine would be cut, bringing the number of redundancies at the mine to 500 for the past 12 months.

Mt Arthur currently runs four crews of haul truck drivers, with 80 trucks operating each shift.

The world’s biggest iron ore producer, Vale, has announced its intention to expand production despite a falling price. This follows similar announcements by Rio Tinto and BHP.

This expansion in production by the three largest iron ore exporters in the world, accounting for over 60% of the market, is puzzling and it may not be in the best interests of the resource owners in Western Australia and Australian taxpayers generally.

Why would firms pursue such a strategy? Western Australian Premier Colin Barnett has suggested the big miners may be flooding the market to reduce the price and drive higher-cost suppliers from the market.

Indeed, Vale’s CEO has indicated the objective is to displace competitors’ quantities. This is plausible as there are many producers that are marginally profitable at current world prices. They will likely exit the market if prices are reduced further.

Given the big miners’ market share, it stands to reason that higher production volume will have a negative impact on iron ore prices. Perhaps the big miners hope that once higher cost producers exit the market, prices may rise again.

However, there many reasons to suggest such a view is too simplistic and this strategy will not work.

Crucially, iron ore production is by and large a mining and extraction activity. This means underground resources do not disappear if a high-cost miner exits the market. Equally, once resources are mined, extracted and sold at a potentially low price, the resources are gone and its owners will not be able to enjoy future higher prices.

It may make sense for the big miners to ramp up production now, despite causing a reduction in prices, if there are particular reasons to believe the demand for iron ore will decrease in the future. If this were the case, then it might be better to sell now, even if at reduced prices, vis-à-vis selling in the future at even lower prices. But this is unlikely given that many countries in Asia, Africa and South America will still need steel to catch up to the level of development of richer countries.

Is this just supply and demand at work? Is it a case of lower-cost producers vying for larger market shares even if this happens at the expenses of these companies’ shareholders? Unfortunately this ignores the interests of those who own the resources.

Iron ore resources are owned by the state (that is, by the people). The economic rents – the income derived from the ownership of a resource that exists in fixed supply – are captured in two different ways in Australia.

The Western Australian government charges (ad valorem) royalties on the value of iron ore sales. By increasing production, causing prices to fall, the big miners’ action will affect the value of the royalties captured by the government. Even if the big miner’s revenue rises due to quantities rather than prices, royalties may still fall if other Western Australian producers exit the market.

Similarly, Australians at large benefit from the tax revenue collected by the federal government. As the corporate tax is levied on accounting profits, lower iron ore prices may mean lower tax revenue as well.

Again, even if prices increase in the future, Australian governments will not be able to fully capture additional revenue as many high-cost producers are located in other jurisdictions.

Mining companies own capital that can be driven harder, as well as owning the mining rights. Managers may be tempted to increase production and enjoy a higher return on capital even at the expense of not maximising the value of the resource over the life of the mine.

The public, however, captures the value of the resources through ad valorem royalties and the corporate tax system. This means the public would benefit from actions that maximise the value of the resources over the life of the mine.

The challenge for the big miners is how to overcome this temptation of any short-term gains from increasing production to capture market share, at the expense of reducing prices further, resulting in a reduced value for the resources over the life of the mine. The challenge for governments, on behalf of the resource owners, is to continue to challenge the big miners’ thinking as Premier Barnett has done.

Austin Engineering is a leading designer and manufacturer of customised dump truck bodies, buckets and ancillary products used in the mining industry. We are also a complete service provider, offering on and off-site repair and maintenance and heavy equipment lifting services to customers including miners, mining contractors and original equipment manufacturers.

Austin Engineering has developed to new JEC bucket designs for Letourneau wheel loaders.

According to the manufacturer these buckets, the JEC L1850-2 and the JEC L2350-2, can hold approximately 28.3 and 38.2 cubic metres respectively.

The buckets are fully OEM compatible and designed with OEM specifications and bucket design limitations, cutting the potential for warranty implications for operators’ machines.

“Wear and fatigue life are improved through a heavy duty main shell plate,” Austin stated, “and the reinforced headboard provides high impact resistance”.

“Superior strength and resistance to deflection is achieved through a flat base design which provides a uniform bucket floor for grounding leveling and clean-up operations.

“Increased operator protection is achieved through a spillguard extension, along with improved visibility due to the numerous cut-outs in the headboard and the spillguard infill plate.”

The buckets also have increased performance and penetration due to a spade lip design, with a 15 degree edge angle in-lieu of standard 10 degree units.

Both buckets are fully customisable, with their structure having been optimsed by FEA analysis.

Northparkes is a copper and gold mine located 27 kilometres north west of Parkes in the Central West of New South Wales, Australia. Northparkes is a joint venture between China Molybdenum Co., Ltd (CMOC) (80%) and the Sumitomo Groups (20%).

The majority of our employees and their families live in the Parkes Shire, a diverse municipality centered in the town of Parkes, a thriving country town of about 12,000 residents. Parkes’ primary industry is agriculture but growth over recent decades from industrial, transport and mining sectors now means there is a diverse economic base in the town.

Northparkes operates underground block cave mines on its mining leases. Northparkes was the first in the country to use a variation of the cost-effective block cave mining technique in its underground operations. Underground block cave operations include the E26 Lift 2 and Lift 2 North (Lift 2N) block caves as well as the E48 block cave project. Open cut mining campaigns have been undertaken in the E26, E22 and E27 pits

Northparkes’ ore is processed on site to produce a high-grade copper concentrate which is then transported by road train to the Goonumbla rail siding approximately 13 kilometres from the mine. The containers are then placed on to a train and transported to Port Kembla, south of Wollongong, where the concentrate is then shipped to customers primarily in Japan, China and India.

Northparkes Mines owns 6000 hectares of land around the mine, of which the mining lease covers 1630 hectares. The remaining land is actively farmed using best practice farming methods developed and adopted to maximise productivity and quality while conserving water and soils.

As of 1 December 2013 the majority owner of Northparkes Mines is CMOC. Northparkes is CMOC’s first international asset. For more information on CMOC please read the factsheet below.
