The boom is back on, with strong demand for workers in all the hardrock underground mines across Australia. The industry requires people from across the population, for a verity of skills and jobs.

People keep trying to do the things that helped get a job in past booms. The 3day dump truck course is the classic example of this, it worked 25years ago for a short time when the iron ore mines in WA were first hiring. These tickets are non-transferable. This is why there are no TAFE courses in hardrock mining.

Mining is the process of mining stuff out of the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction. Mining can include extraction of metals and minerals , like coal , diamond , gold , silver , platinum , copper , tin and iron. Mining can also include other things like oil and natural gas. Some mining is done by scraping away the soil dirt from the top of the ground.

This is called surface mining. Some mining is done by going deep underground into a mine shaft. This is called underground mining. Some mining, such as gold mining, is done in other ways. Gold can be mined by searching in the bed of a river or other stream of water to remove the flakes of gold. This is called panning or placer mining.

Underground coal mines can reach depths of around 2, feet, while some underground uranium mines can go as deep as 6, feet. There are two types of underground mines. In hard rock underground mines , hard minerals containing gold, silver, copper, zinc, iron, nickel and lead are excavated. Different extraction methods can be used in hard rock underground mines, depending on the kind of deposits that are found.

Soft rock underground mines are the ones that extract coal, oil shale, potash, and other minerals that are hiding inside sedimentary rocks, or soft rocks. Since the deposits found in soft rock mines are layered and not as hard as hard rocks, different underground mining techniques are used. Each underground mine is unique, but they all have at least a few things in common.

They all have access shafts for workers and equipment, recovery shafts to bring excavated rocks to the surface, and ventilation shafts. They also all rely on a communication system between the depths of the mine and the surface. Back in the days, miners used only shovels, and brought canaries with them in coal mines as a warning system. Today, different underground mining technology solutions are used to ensure the safety of the miners, to simplify different operations and to increase the productivity of underground mines.

Due to the tools and the equipment that are being used, as well as to everything related to the safety and the health care of the miners, underground mining is a lot more expensive than surface mining.

The dependency of various high-tech-industries on rare earths is a recent issue — coal, on the other hand, is still one of the leading global energy resources. The revenue of the top 40 global mining companies , which represent a vast majority of the whole industry, amounted to some billion U.

The net profit margin of the mining industry decreased from 25 percent in to 11 percent in Leading mining countries In terms of volume, the most exploited commodities worldwide are iron ore, coal, potash, and copper. China, Indonesia, and India are the largest coal producing countries. China is also the third-largest producer of iron ore. Indeed, China is becoming the top mining country for many commodities, especially for the highly demanded rare earths , of which China produced nearly 58 percent of the global production in As of May , BHP had a market capitalization of Measured by revenue, the top company active in mining worldwide was Glencore , generating some billion U.

On March 30, , Russian nickel explorer Amur Minerals Corporation OTC:AMMCF announced that it was mulling over underground production to increase the life of a mine at its flagship project, the Kun-Manie Reserve. According to the company, the underground operation could result to a staggering six-million-ton-per-year production volume for a year period. It is several percentages higher from its earlier prediction, which was only 11 years.

Underground production is estimated to be Enhancing its opencast operations with an underground mining could potentially increase the Kun-Manie mine site by at least 19 percent. Selection always depends on the geometry properties of the deposit, its position, location, and type. Generally, startup explorers and miners begin with open-pit mining because it is cheaper, easier, and safer.

Since it is a process wherein ore and minerals are extracted from deep underground, it does not incur large damages to the surface environment of the mine area. Underground mining. Typically, mining companies opt to conduct underground excavation when the mineral or ore to be extracted becomes impossible to extract through surface mining. Underground mining is often utilized by mining firms to extract more ore and minerals. Higher production volume mitigates the costs spent on initiating the very expensive method of underground mining.

For a better understanding, ScienceStruck gives more differences between these two methods. There are two ways to extract a mineral — by digging it up, or accessing it by tunnels. In the past, coal miners carried a caged canary bird while working in underground tunnels.

If the canary died, it was a sign that toxic gases were present inside, and the mine need to be evacuated. Would you like to write for us? Well, we’re looking for good writers who want to spread the word. Get in touch with us and we’ll talk
