Surface Mining Techniques Surface mining of coal is characterized by the use of large, capitalintensive and efficient mining equipment. First, the overlying soil and rock layers (overburden) are removed. The coal is then fractured with explosives or machines, and loaded onto vehicles for haulage from the mine site. Finally,
In today''s technologicallyadvanced society, mining techniques are always improving. For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers.
These mining categories are: strip mining, openpit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to subsurface (underground mining) by mining companies for several reasons.
Feb 23, 2018· In all methods of surface mining, first, the overburden is stripped off using, 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.
Conventional Methods of Surface Mining. Openpit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.
Researchers at the National Institute for Occupational Safety and Health, Spokane Research Laboratory, studied technology and methods that could reduce accidents involving surface mining equipment that collides with other vehicles or workers, or drives over an unseen road edge.
There are several methods of surface mining including openpit, stripping, dredging and mountaintop removal. This paper will focus on openpit surface mining, which involves removing ore from a large hole in the ground (sometimes referred to as a borrowpit). A combination of explosives and excavating equipment create surface mines by sequentially
Based on mining method, strip mining is the largest application market for surface mining equipment. The market for surface mining equipment used in strip mining is expected to witness slow growth in the future due to increasing limitation on coal mining activities and coal based power plants.
