Geoscience Australiareported in 2017 that there are at least 391 operating mine sites in Australia spread across a wide variety of resources. Gold makes up 128 of the total while coal mines total 91. There has been extensive growth in iron ore over the past several years with mines totalling more than 40. By volume, Australias two most important mineral commodities are iron ore of which 97% is mined in Western Australia and coal, which is largely mined on the east coast, in the states of Queensland and New South Wales.

Australian mining resources include: 1. Iron ore Australia is the worlds largest supplier; 2. Nickel  Australia was the worlds fourth largest producer in 2015, producing 9% of world output. 3. Aluminium Australia was the worlds largest producer of bauxite in 2015 , and the second largest producer of alumina after China. 4. Copper Australia was the worlds 5th largest producer in 2015 5. Gold Australia is the second largest producer after China, producing 287.3 metric tonnes in 2016, 9.2% of the worlds output. 6. Silver In 2015 Australia was the fourth largest producer, producing 1,700 metric tonnes, 6% of the worlds output. 7. Uranium  Australia is responsible for 11% of the worlds production and was the worlds third largest producer in 2010 after Kazakhstan and Canada. 8. Diamond Australia has the third largest commercially viable deposits after Russia and Botswana. Australia also boasts the richest diamantiferous pipe with production r...

There are many different types of mining methods applied to Australian mining operations. Mining methods are often dependent on resources types with coal and iron ore the two most mined commodities we have included information on the Australian mining methods for those commodities.

The Australian mining industry has ebbed and flowed with economic cycles. The Goldrush of the 1850s led to the increased importance of mining to the Australian economy. Other post WWI and WWII periods saw considerable growth. In recent times the Australian mining industry experienced an extended phase of strong growth from around 2005 to early 2013 and again from 2018 into 2019. There has been considerable recent investment and construction of major projects.

The Australian mining industry uses major capital goods for undertaking mining works including: Dozers, Excavators, Shovels, Trucks, Drills. There are typical variants of these for surface and underground mining. While Australian manufacturers have developed some substantial capital equipment, the vast majority is sourced from overseas and assembled here by the subsidiaries of foreign capital equipment companies. An overwhelming majority of heavy/earth moving equipment is imported. The US is one of the largest exporters of mining equipment to Australia, with Japan, China and Germany being other important sources of imported equipment. Major players such as , Komatsu, Wirtgen, Joy Global and Liebherr have a strong presence in the market. Smaller scale local manufacturers cater to niche and specialized markets and are particularly competitive in mining related software, fine coal cleaning and process control, and strata reinforcement technology. There are more than 550 Aust...

Australian mining is one of the safety mining industries globally. Australia has progressively improved its safety record through the development of a risk based approach to all mining related activities. The industry was traditionally heavily unionised and subsequently miners working conditions and slary levels were one of the best internationally. In 2005, Australasian Mine Safety Journal was established to provide sharing of information and best practices to the industry. Australian mining safety technology has been at the forefront of the world particularly in gas detection and monitoring, hazard identification and recording and a range of safety monitoring technologies and sensors. Some notable disaster have also occurred in Australian mining industry operations. New Australian Gold Mine Creswick The Creswick Gold mine in the Victorian goldfields was the site of The New Australasian No.2 Deep Lead Gold Mine. No one could have imagined that in the small but prosperous town in 1...

While several Unions represent workers across the Australian mining industry, the CFMEU is most well known. The CFMMEU has been actively representing mining and energy workers now for more than 150 years and is arguably one of the most powerful union movements in Australia. It represents members working in underground and open cut coal and metals mines, the generation, transmission and distribution of electricity , the petrochemical industry and iron ore mining and transportation. The CFMEU has been a strong advocate for safety and removing workers from dangerous conditions in workplaces across the Australian mining industry. It has a current focus around casualisation in the industry where a number of the workforce have believed to forgo the right to maintain employment relationships. The CFMEU says it fights to continuously improve workplace health and safety, for fair workplace deals that recognise the contribution of mining and energ...

What are the different types of mining and how do they differ?

As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesnt require tunnelling into the earth and is a simple method of mining that yields high production rates. The Fimiston Open Pit and the Newmont Boddington Gold Mine are two of the largest open pit mines in the world, measuring over 3.5km long, 1.5km wide and 570m deep. Both pits are located in Western Australia and produce 28 tonnes of gold per year.

Utilising the mammoth strength of Bucket Wheel Excavators, moving up to 12,000 cubic meters of earth per hour, Surface mining is the process of seam mining coal and ore from the land. In this process, any unwanted earth or soil is stripped from the land and any ore or mineral that is sought after is found relatively close to the surface of the site. Because of the land decimation that occurs in Surface mining, this form of mining is controversial. Surface mining often leaves behind large areas of infertile land and waste rock as 70% of the mined earth is waste materials.

Underground or Sub surface mining involves the digging of a network of shafts and tunnels into the earth to reach and extract the deposit of ore or mineral beneath the earth. In comparison to other methods, underground mines impact less on the environment and are much more harmful to those working within them. In the past, underground miners utilised shovels, axes and carts to retrieve valuable materials at great cost to their health. Canaries were often utilised as an early indication system of toxic gases in the mines as they would quickly perish of oxygen levels were harmful. In modern practice, underground mines are pre assessed for oxygen toxicity levels and a system of ventilation machines and protocols are in place to ensure workplace safety. Moreover, relative to other forms of mining, underground mines excrete much less waste rock when accessing the ore. That being said, though, the process is a lot more expensive and difficult than other forms. Geologists and Mining Engine...

A rarely used process of mining material, In Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In Situ Uranium Mine. This solution works by changing the pH and Oxidation levels of the ore, leading to the ore breaking down and becoming easily extracted. For example, Sulfuric acid is generally used when In Situ Mining for copper. Looking for Mining Equipment? Visit here for more information
