SURFACE MINING METHODS AND EQUIPMENT
2. Equipment Selection in Surface Mining Selecting Fleet Type For ore transportation at a surface mine, different fleets can be used. Shovel truck and loader truck are mostly utilized fleets, however; with respect to existing circumstances at the mine, equipments like dragline; bucket wheel excavator; inpit crusher; and conveyer too could

2 #0183;#32;Draglines are by far the most commonly used overburdenremoval equipment in surface coal mining. A dragline sits on the top of the overburden, digs the overburden material directly in front of it, and disperses the material over greater distances than a shovel.

#0183;#32;Harmful causes to earth surface with the diverse process of mining. Despite the strict rules enforced by the government and the use of new technologies to reduce the risk to the planet and widespread ideas of the green world, mining companies are still using lots of natural resources.
equipment required for coal mining Coal mining employs surface and underground methods to extract coal. . There are two basic methods to remove coal: surface mining and underground mining. .
Mining Methods, Surface mining ) PLACER MINING Placer deposits are concentrations of heav y minerals, usually w ithin loose alluvium that can easily be
Truck and shovel mining method is the most flexible mining method and therefore better suited to geological complex deposits, varying overburden depths and thicknesses, and
In this situation, typically in multiseam mines, truck and shovels are introduced to create an integrated mining sequence, which operates in tandem to generate a cost effective and efficient mining sy stem (Fox, 2011). Draglines are the lowest cost overburden removal equipment in common use.

Coal mining Choosing a mining method | Britannica
The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines require washing in a coal preparation plant.
section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1. Underground Mining Methods Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground
In all methods of surface mining, first, the overburden is stripped off using earthmovers. Then, bucketwheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation.
expensive surface mining method. Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside.
Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Largescale 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
