Coal Mining in India

The average mechanised mine in India had an out-put of 3.8 tons per man-shift in 2008, while manual mines operate on levels of 0.4 tonnes. In comparison, the United Colliery in Australia reports to achieve an output per man shift of 65 tonnes. In order to increase productivity there is a shift towards large scale open pit mining.

Significance and measurement of coal mine productivity

Productivity is usually referred to in terms of output per machine, output per labor hour, or more common in coal mining, short tons per man (or labor) shift. Labor productivity (short tons per labor shift) is most commonly used in the coal mining industry as a measure of changes in labor efficiency and as an indicator of the efficiency of the ...

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. In many mineral industries, like coal industry, in open cast mines, coal can be extracted only after removing layers of soil, stone etc.

Historically, mining accounted for below 5 percent of Australia's GDP. During the boom, this rose substantially, reaching 9.8 percent of GDP in 2008–9. The surge in commodity prices during this period resulted in rapid growth in the value of Australia's mining output. However, mining output volumes did not grow at the same pace.
