Underground coal mining and surface mining of other minerals depend on high-quality augers. Since the mid 1950s, augers have been an integral aspect of both underground and surface mining. At Falcon Industries, we take great pride in providing custom built augers that the mining industry requires to complete its operations efficiently and safely.
Auger mining is a 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.

Abstract. Auger mining of coal, developed since World War II, produces 6 million tons of coal a year, according to this report based on field studies of 8 auger-mining operations in 5 different coal beds, Upper Freeport and Upper Kittanning beds in Pennsylvania, Lower and Upper Kittanning, Pittsburgh, and Winifrede beds in West Virginia, and Pittsburgh (No. 8) bed in Ohio.

Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique ...

Auger mining. Auger mining is usually associated with contour strip mining. With this method, the coal is removed by drilling auger holes from the last contour cut and extracting it in the same manner that shavings are produced by a carpenter's bit. Coal recovery rates approach 60 percent with this method. The cutting heads of some augers are ...

Surface mining is further classified as strip mining, auger mining, open-pit mining, and mountain removal mining. in the mid-1940s with auger mining. However, it is only recently that interest in the technique has been shown by coal miners elsewhere. Also, compared with auger mining where a fixed height is cut, it offers a variable mining height.
