Surface Mining Surface, or open pit, mining of coal is done where the overburden is relatively shallow. Large earth-mov- ing equipment, draglines (figure 13), or shovels are used to remove the fractured overburden from the coal (figure 14). The coal is then typically broken up by blasting it with explosives. The coal is loaded into

nonmetallic mineral mining and quarrying. Industries in the mining (except oil and gas) subsector primarily engage in mining, mine site development, and beneficiating (i.e., preparing) metallic minerals and nonmetallic minerals, including coal. Of these subsectors, there has been extensive research conducted on coal mining.
Currently, almost all nonmetallic minerals (more than 95 percent), most metallic ores (more than 90 percent), and a large fraction of coal (more than 60 percent) are mined by surface methods (Hartman, 1987). However, as surface mineral deposits are exhausted, underground mining will inevitably become more prevalent.
Nonmetallic mining operations must also get DNR water permits, and some need air permits.
