In indiana is auger mining considered underground mining

How is coal mined in Indiana? – IN.gov

Underground mining accounts for the balance of extraction, or about 35 percent. An opening is cut in to the ground and a long entry formed down to the coal seam. All of the work is performed below ground and the coal brought to the surface by conveyor belts. Underground mines in Indiana usually range from 200 feet to over a thousand feet in depth.

Trends in underground coal mining in Indiana

During 1979 about 26 million tons of coal was produced in Indiana, 97 percent of which was derived from surface operations. Surface mining has not always played this preeminent role; underground mining was once the major method of coal extraction in the state. Since 40 percent of strippable reserves has already been exploited, surface mining in Indiana is almost certain to decline within a few ...

Auger mining coal mining Britannica

Auger mining, method for recovering coal by boring into a coal seam at the base of strata exposed by excavation. Normally one of the lowest-cost techniques of mining, it is limited to horizontal or slightly pitched seams that have been exposed by geologic erosion. Augering is usually associated with contour strip-mining, recovering coal for a ...

Coal Mining in Indiana

Coal Mining in Indiana When you think of coal mines and the miners who descend into the earth, the hills of West Virginia, Kentucky and Pennsylvania probably come to mind. It may be somewhat surprising, then, to learn that coal mining is a significant source of employment and wages across southwestern Indiana, and in one county in particular.

Mining - Underground mining Britannica

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

Auger mining: Form of underground mining that uses an auger (rotary drill) to penetrate, break and transport drilled material onto a waiting conveyor belt. Usually employed to recover remaining material in deep overburden areas that cannot be reached economically by further contour or area mining. Base metals: Any of the non-precious metals.

Glossary of Mining Terms - Coal Education

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
