Mining 2010 and Beyond conference visits Queensland coalfields

Reed Exhibitions has announced a major two-day mining conference to be held as part of the Queensland Mining and Engineering Exhibition (QME) in Mackay in late July.

The conference, with the theme Mining 2010 and Beyond: maximising alliances, partnerships, technology and innovation for a sustainable future, will be held at the new Mackay Entertainment & Convention Centre on July 27 and 28.

QME – which attracted some 500 exhibitors and more than 10,000 trade visitors when last held in 2008 – will be held at the Mackay Showground from July 27-29, 2010.

“The Mining 2010 and Beyond conference will combine a mix of ‘big-picture’ presentations, covering the major issues and challenges facing the mining and resources sectors, with a range of management-focused workshops and papers,” Julie Boyd, Chair of the Mackay Area Industry Network (MAIN) and conference moderator, said.

“Our aim is to provide a ‘must-attend’ conference that will give attendees – whether from the Central Queensland coalfields, or the wider Australian mining industry – access to the latest developments, trends and ideas.

“We are currently talking to some very high-profile people within the mining sector and at the highest levels of government about participating in the conference, as well as those using and applying world-leading techniques and practices in actual Australian mine sites,” she said.

Soren Norgaard, Exhibition Manager with Reed Exhibitions, said the conference would be a major drawcard for Mackay during QME week, both to the exhibition and the region.

“The exhibition, the conference and other related events we will be announcing mean that Mackay in July will offer the Queensland resources sector a full package of exhibition, information and networking throughout QME week,” he said.

Specific details of the conference program will be announced later this month.

A “Secret” Subway Stop

Hidden deep under New York City, a "secret" subway stop is drawing visitors. The Big Apple's City Hall station, a beautiful structure that opened in 1904, but has been out of use for decades, can be seen by riders

Jalopnik writes that if you want to check out this long-forgotten station, one of the "most gorgeous gems in the world of mass transit," you'll have to take the 6 train and then stay on board. Jalopnik elaborates, "The 6 train used to make all passengers leave the train at the Brooklyn Bridge stop, but no longer. If you have a little extra time, you can stay on the train and view the City Hall station as the train makes its turnaround."

So why was the station closed so many years ago? Motobullet explains that the station's curved tracks played a part in its closure. When subway cars moved their doors to the center, it "created an dangerous gap between the exit point on the train and the platform." There were plans to make the stop into a transit museum, but security concerns, especially following the events of 9/11/01, put the plan in limbo.

Now, though, folks who take a little extra time amid New York's hustle and bustle can spy the station with their own eyes.

Quartz crusher is a mining machines for quartz stone

Looking for Quartz crusher ?

About quartz you should know:
The traditional way to distinguish quartzite from sandstone is that unlike sandstone, quartzite breaks through, not around, the quartz grains, producing a smooth surface instead of a rough and granular one.
Quartzite are snowy white, less often pink or gray. Quartzite stone generally has blocky structure, which contains small amounts of feldspar, mica stone, amphibole, pyroxene, etc. They yield a thin and very barren soil and people usually find them in hills and mountains and can be used as building materials or railway ballast stone.
c :
Quartz crusher is the major mining crusher equipment to crush quartzite stone, and SBM is the major mining crushing machine manufacturer in China. Usually, quartz crusher can be called as quartz grinder.

Some news about quartz crusher using in Magenta Gold Mine:
Mining of the Magenta Reef commenced as an open cut operation in 1860. Earth, rock and quartz were excavated and carried out by horse and dray. As the open cut was extended, it was also widened.
Follow the gravel track around the northern end of the open cut to the fenced open stope. This enlarged tunnel or drive was worked at a depth of 30 m. The gold bearing ore was removed by excavating the roof of the drive and mining upwards.
Walk along the track to the site of the mine's quartz crusher or stamping battery. You might see part of the concrete foundations.
About 50 metres further south is the site of Place’s quartz crusher, the timber foundations can still be seen. This crusher operated independently of the Magenta Mine.

Opening up new open cuts

While many predicted the threat of a heavy mining tax would stop, or at the very least slow the resources industry, clearly some were not listening.

Expanding its already massive coal arm, Rio Tinto has officially opened Australia’s newest open cut thermal coal mine at Clermont.

Construction on the mine and associated infrastructure started back in 2007, with the first shipment of coal delivered in May this year.

Holding a 190 million tonnes of coal, the mine has an expected life span of 17 years with production expected to peak at more than 12 million tonnes per year of export coal and 100 thousand tonnes for domestic use when the mine reaches capacity in 2013.

Rio’s global chief executive energy Doug Ritchie told the hundreds gathered at the opening of the mine that it was special for many reasons.

“It has five coal seams that are particularly thick, the Wolfgang seam is 35 metres thick on average and up to 100 metres in some places.”

With the seams located under a large volume of overburden, Rio built it’s only inpit crusher/conveyor system on site.

“This will reduce annual truck running costs by more than 35%,” Ritchie said.

While the majority of the mine’s coal can be crushed and sold directly for export markets such as Korea, Japan and Thailand, it also has a small coal processing plant that uses paste thickening technology.

Using this technology eliminated the need for a conventional tailings dam on site.

Now that the mine has officially opened, Clermont is aiming to continue to play a strong part in the local community’s future.

In 2009 alone, Clermont contributed more than $610 000 to community projects.

It is looking to replace the role of the neighbouring Rio Tinto Blair Athol Mine, where closure is currently planned for 2016.

The Blair Athol mine has been central to the region over the past 25 years and Clermont Mine will extend this into the future, Ritchie said.

Clermont will also send its processed coal along a newly constructed 13 kilometre conveyor to the older mine, using the existing equipment at Blair Athol for stockpiling and railing to port.

More than 10 000 applications were received during the mine’s recruitment drive, with people such as Clermont local Brad Perrin and Rebecca Chilcott finding jobs at the site.

Having worked at both Blair Athol and Clermont as well as growing up nearby, Brad Perrin had a unique perspective.

“Rio Tinto has built a good relationship with its near neighbours and done their utmost to minimise the impact on the area,” Perrin said.

Some of this minimisation includes the protection of endangered plant species found near the site.

The mine has entered into an agreement where it will sponsor University of Queensland research into one of Australia’s rarest plants, the Belyando Cobblers Peg, and how to best re-establish it.

It is also part of long running research into wild koala populations in the region.

Rebecca Chilcott found her new job, driving haul trucks and water carts daunting at first but says she has really enjoyed the challenge.

During construction, the mine won an Australian Mining Prospect Award for its proactive approach to hiring women.

Currently women make up 27% of the site’s workforce, well above the QLD state average of 11%.
The mine aims to have a total of 380 people employed when fully operational.

The Greens are declaring it will oppose the conversion of coal into liquid in the Hunter Valley.

This follows questions to the NSW parliament regarding investigations into the Denman-Scone area from Greens senator Lee Rhiannon.

After Rhiannon uncovered a report from 1981 that outlined the area had suitable feedstock for coal liquefaction, she voiced her concern over what outcomes it may have.

"Where we're worried, it can just further lock us into a dependence on coal power. That's just bad news in terms of emissions, in terms of local environmental impact," she said.

The Greens will now push this issue into the Federal arena.

"We will continue to track this and actually look at it federally, because the study cost $3.6-million with both the Federal and State Governments paying.”
