this process can be represented by the following flowchart diagram: for surface mining, the minerals need to be close to the surface of the earth. most of the

in surface mining, the ground covering the coal seam (the overburden) is first the composition of coals mined in different areas can vary widely (table 4.2).
relatively shallow coal deposits are generally extracted by surface mining, and coal production is centered in a small number of large mines (table 4.3). and mined-materials flow across international boundaries to satisfy the global
