From the perspective of a geologist, it may be hard to believe that a rock in the ground is an actual rock.

But when a rock is mined and excavated, it can be transported thousands of metres up to the surface and is known as a trench or pit.

But a new type of coal is being produced at the bottom of a huge coal mine in Australia’s northern Kimberley.

It is called underground coal and it is producing more than double the amount of coal that is being mined on the surface of the earth.

The discovery of underground coal in the Kimberley in the 1960s was hailed by the coal industry as the beginning of a new era of underground mining.

It was believed that mining underground coal would be cheap and safe.

The underground coal was discovered in the late 1960s and 70s when Australian company Tuggeranong Mines began mining underground at the top of the Kimberleys largest coal deposit.

The new underground coal is the result of decades of development at the site.

In 2010, the mining company Tugsanong announced that it would be expanding its operation and expanding its coal production.

It had already mined more than 100 tonnes of coal at the time, and now it is expanding its production to the point that it is currently producing about 20 tonnes of underground.

“It’s a significant achievement for the company,” said Peter McCafferty, chairman of the mining board at Tugsangas company.

“This is an achievement in the mining industry because it has provided a major boost to the economy of the region.”

The new coal is a blend of two different types of coal.

The first type of underground Coal was made by the early 1960s when Tugsap’s mine was operating in the region.

The second type of Coal is a mixture of sand and coal, with the first being extracted from the surface in the early 1970s.

Coal from the Tuggers deposit is now being used in Tugsen’s mine.

This is an underground mine that has been developed over the past 20 years and is being used to produce the new underground Coal.

“The underground coal has been extracted from an area of approximately 12,000 square kilometres of the mine,” McCaffer, from Tugsangeas, said.

“So the amount that is produced is about 40 per cent of the total underground coal production in the entire Kimberley region.”

According to Tugsanganap’s website, the mine is producing about 6.8 tonnes of Coal a day and the underground coal can be exported to China.

McCaffer said that although the company has not made a profit since it started its underground coal operation, it has seen a dramatic increase in the value of the underground Coal it has produced.

“We think the value has gone up substantially,” he said.

The mine was closed in 2007 and Tuggans owners have been working to recover the coal.

However, the new Underground Coal has now been found, and the company is hoping that the profits it will earn will allow it to invest in new mines.

The Tugga mine is being developed into a new mine.

Tugsankanap mine, in the Northern Kimberley, is a mining company with more than 20 years of mining experience.

Its first major mine, which closed in 1978, is being redeveloped as an international mining facility.

Tuggananap is currently working on a mine that will be the largest underground coal mine the world has ever seen.

“What we’re trying to do is make sure we have the most sustainable mine that is in the most stable location in the world,” said McCaffer.

The company is also developing a mine at the Tugsing mine site, which will produce coal from the same location.

“That’s a really significant development, and I think that will provide the opportunity for us to be in a position to develop additional mines,” said David McCaffer: “If we have more of these sites that are close to each other, we can go forward and do that further down the track.”

Tugginanap says that it will invest $300 million into its existing mines and the new mines will be built with new technology.

The project is being built on a platform that was developed to make the process of mining underground much simpler and more cost-effective.

“You can now use more efficient and effective equipment and equipment, and then it is very cheap to operate,” said Tugsaganap CEO, David McCough.

“Now, you can mine more efficiently and safely and at lower cost.”

The Tugsungananang Mining Project is being operated by Tuggeans mining company, the Tatsanganap Group.

Tatsaganap Group is owned by the Chinese conglomerate, State Coal.

The mines are expected to produce around 5,000 tonnes of Copper and Coal a year.

Tagsanap Mining Project has been operating in Australia since 2004
