what are the advantages of surface mining of coal. Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination.
One of the major benefits to open pit mining is the increase in efficiency over deepshaft mining techniques. Because mining occurs at the surface, no space restrictions from narrow tunnels and shafts affect the rate at which ore can be extracted.
MINERAL RESOURCES . Their Importance: · Essential for industrial and economic development of nations. · Copper, tin iron ore were essential to the ancient metalusing cultures of the Bronze Iron Ages. · Used in construction, engineering and chemical industries. · Railways, computers, cars, skyscrapers etc in modern society depends upon the exploitation of mineral resources.
The advantages of surface mining are: It is cheaper to extract the ore or metal than underground mining Less chance of workers dying from toxic fumes, therefore it is .
Injuries, Illnesses, and Fatalities in the Coal Mining Industry. Coal mining is part of the Mining sector along with other mining and extractive industries such as oil and gas. Coal mining is further divided into Bituminous coal underground mining, Bituminous coal and lignite surface mining, and Anthracite mining.

Surface mining (strip mining, open pit mining, mountain top removal) Advantages: cheap Disadvantages: removes all overburden (trees, soil, rocks, etc.); obliterates natural communities b/c everything has been removed; leads to erosion; causes sulfuric acid runoff; Subsurface mining Advantages: removes the least amount of unwanted material so less waste
Aug 01, 2007· Answers. Best Answer: Advantages of underground mining: (1) Less loss of land (2) Minimum dust pollution (3) Minimum noise pollution (4) Lack of nearsurface deposits may make underground mining the only method. (5) Unfavorable geologic structure may require that a surface mine move underground to follow a particular bed.
Lignite is more accessible than other types of coal because lignite veins are located relatively near the surface, eliminating the need for underground excavation in tunnels. Surface mining also eliminates the risk of methane or carbon monoxide buildup, a primary safety concern in underground mining. Lignite mining is not totally without risk.
The technique of surface mining gained momentum in the 16th century and has been widely prevalent at a global level, especially in North America. The surface mining market can be segmented on the basis of methodology, minerals extracted, and the geographical locations of the surface mining .
Apr 16, 2008· Answers. Especially in Europe not too long ago, coal mining was not more profitable and lucrative from the economical point of view. Therefore many collieries were closed. This affected GB, France, Germany, Spain and other European countries. It continued to be profitabe in China cus. miners earned a misery.
Table 2 provides some examples of the Australian surface coal mines. Figure 3 illustrates a typical overall mining sequence of strip mine operation. Mining method description Example mines Multiple seam, steep dip, truck and loader, strike cut haulback mine with truck and loader coal mining.
Like other surface mining operations that remove materials, pit mining operations scar the landscape, destroy habitat, and pollute the air with dust and particulates. Placer mining The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed.
Jul 01, 2016· Strip mining clears trees, plants and topsoil. Mining companies scrape away earth and rocks to get to coal buried near the surface. Mountains may be blasted apart to reach thin coal seams within, leaving permanent scars on the landscape. In this way, strip mining destroys landscapes, forests and wildlife habitats.
