Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Large-scale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and
In Australia, nearly 80% of coal is produced from open-cut mines in contrast with the rest of the world where open-cut mining only accounts for 40% of coal production. Open-cut mining is cheaper than underground mining and enables up to 90% recovery of the in situ resource. Coal may be used without any processing other than crushing and screening to reduce the fragments to a useable and
Coal is mined in every state of Australia. The largest black coal resources occur mainly in Queensland and New South Wales. About 70% of coal mined in Australia is exported, mostly to eastern Asia, and of the balance most is used in electricity generation. Coal production in Australia increased 13.6% between 2005 and 2010 and 5.3% between 2009 and 2010. In 2016, Australia was the biggest net exporter of coal, with 32% of global exports (389 Mt out of 1,213 Mt total), and was the fourth-highest producer with 6.9% of
Longwall mining is one method of pillar extraction, now the most common method in use in Australia, and probably worldwide. Before longwall mining methods had been developed to operate satisfactorily in most conditions, a lot of pillar extraction was carried out using continuous miners, and such methods are still in use in places for a variety of reasons.

Coal is abundant in Australia. Australian coal is high quality and is suitable for use in steel mills and as an energy source for power generation; The world needs coal to power its energy generating requirements. Australian mining companies have invested billions in new technology and are preparing for new mines to be developed.
INTRODUCTION. The intended purpose of this Website . is to provide a reference document for all aspects of underground coal mining in Australia (though there may be references to overseas practices where these could be of interest).. The aim is to be of use to all levels of expertise from people with no, or at least a very limited knowledge of mining through to practicing mining engineers
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when

Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique

Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
