Appendix E: Coal Mining and Processing Methods Coal ...

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...

surface coal mining history The Pop History Dig

May 31, 2017  Coal has been mined in Ohio since the early 1800s, initially with crude mining techniques working surface outcroppings, to more sophisticated mechanized technologies that evolved following WWI and WWII. Most of the mining in Ohio through the 1930s was in deep mines or shaft mines that bore into mountainsides.
