Coal is recovered from the earth by surface mining or deep mining. Surface mining, or strip mining, is less expensive and usually occurs on flat land. Deep mining requires digging shafts and tunnels to get to the coal seam. Automation of deep mining has helped to counter its safety and health hazards.

Facts About Indiana Coal

Surface or strip mining is the preferred method of coal extraction in Indiana due to the relatively shallow depths of coal seams here. First, the coal is uncovered by earthmoving machines, such as scrapers or bulldozers. Then draglines will strip off the earth and rock (overburden) that covers the coal.

Coal is extracted from Earth using one of two major methods: subsurface or surface (strip) mining. Subsurface mining is used when seams of coal are located at significant depths below Earth's surface. The first step in subsurface mining is to dig vertical tunnels into the earth until the coal seam is reached.
