Open cut coal mining equipment used in Australia [13] 2. ABOVE GROUND / OPEN CUT COAL MINING ALTERNATIVES The present paper is focused primarily on the surface, or open cut or opencast methods commonly used in coal mining within Australia, with an emphasis on what conditions would best suit a particular method.

For any industry to be successful it is to identify the Hazards to assess the associated risks and to bring the risks to tolerable level. Mining activity because of the very nature of the operation, complexity of the systems, procedures and methods always involves some amount of hazards. Hazard identifiion and risk analysis is carried for identifiion of undesirable events that can leads ...

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the loion. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of ...

Open cast mining is usually associated with coal or other tabular deposits that are more or less flatlying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut. Therefore, reclamation occurs concurrently with other mining activities.

Coal is mined either by surface methods (opencut or opencast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).

20/12/2017 · OPEN CAST MINING. Open cast or 'open pit' mining is a technique of extracting gemstones, such as Diamond and metal ores, like gold and silver, from the surface of the earth by digging downwards, eventually creating a pit. This method is used when the gems lie near the surface of the ground and the earth covering the gemstones is relatively thin. Open cast Diamond mines can be .

25/03/2018 · Surface mining is more economical than underground mining. It is most commonly used in the US. Because most of the coal is found just under the surface, reclaiming the land after the closure of mine is far simpler. The different types of surface mining that can be used are: 1. Strip mining 2. Auger Mining 3. Openpit mining 4. Mountain removal ...

Cast Blasting: Throw blasting or cast blasting is described as the controlled placement of overburden by drilling and blasting to achieve the optimum overburden removal cost. The technique is suitable for use with large or small draglines and can be adapted for shovel and dragline operations in conjunction with tract dozers to place upto 40% of the overburden in final position.

cycle in openpit mines (Source: Bagherpour, 2007) The similarities between South African and Indian coal mining methods play a significant role in the capital and operating cost structures. South African roomandpillar mining operations are at shallow depths (generally less than 100 m) while the average range in India is about 300 to 350 m (Xie, 2008). Mining costs in Indian mines are about ...

Blasting methods use explosive energy whereas ripping operations utilize mechanical energy generated by a bulldozer and transmitted to the ground through a ripper. In the assessment of rippability of a rock, the single value of the seismic velocity can be shown to be a misleading parameter. The decision regarding rock rippability should be based on a better understanding .

In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).

Open cast (strip mining) method in surface mines has obtained rapid development worldwide in recent years. In China, there are a number of mining areas, the occurrence conditions of which are suitable for appliion of open cast method with draglines. The open cast method in surface mines combines overburden excavation, haulage and dumping operations with one equipment. The annual stripping ...
