coal mining mechanization

e-WV Coal Mine Mechanization

Mechanization of West Virginia’s coal mines took place gradually throughout the first half of the 20th century. Traditionally, coal mining involved the distinct steps of undercutting the seam, then drilling and blasting the undercut coal into manageable pieces, and finally loading and hauling the coal to the surface. The complexity of these tasks and the tight spaces encountered underground ...

Coal Mine Mechanization - A Need of the Day

Mechanical aids to coal mining had been employed long before the mechanization trend got underway. However, these earlier aids to mining merely supplemented the miner's pick and shovel, whereas mechanization as we know it today aims at supplanting manual labor to the fullest extent possible. The early aids to coal mining

Coal Mining - an overview ScienceDirect Topics

Coal mining, particularly in the case of open-cut mines, requires that large areas of land are temporarily disturbed, and perhaps withdrawn from other productive uses such as agriculture, while the process of coal extraction is under way.The land may, however, be returned to productive use after mining or even while mining in other parts of the area is still in progress (Figure 1.2).
