Coal Mine Mechanization. Mechanization of West ia'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.
