This 7-foot machine, now operating in Eastern Kentucky, is the largest coal auger in the world. Smaller augers are used where the overburden consists of massive Sandrock and where the coal seam is too thin for strip mining. Some of these small sized machines use bits ranging from 24 to 84 inches in diameter, including intermittent sizes ...

Cleaning: After each use—remove excess soil, rocks, and debris from the auger's flighting—cutting edges, and other components. Use a pressure washer or high-pressure air to thoroughly clean the auger. Pay special attention to areas prone to buildup, such as the auger's teeth or cutting blades.
The drilling tool is the mining mechanism of the auger miner. Its structure and working sketch were shown in Fig. 1 and Fig. 2 respectively. As shown in Fig. 2, the drilling tool is driven by the main engine and performs drilling in the coal seam.Specifically, five drilling heads initially cut the coal seam, then the broken coal will be transported out …

Auger Mining. Auger mining is a method for the extraction of coal by the boring of an auger into a coal seam. This is usually associated with open-pit or strip mining when it becomes uneconomic to recover coal due to excessive depth and overburden removal. The use of an auger is controlled by the dip of a seam and the engineering …

Auger mining uses large-diameter drills mounted on mobile equipment to bore into a coal seam. Holes are horizontally drilled at regular intervals to depths of as much as 1,000 feet. As the cutting head of the auger bites into the coalface, the cut coal is carried out by the screw portion of the bit. Once the hole is mined to its required depth ...

Definition of auger mining. A mining method often used by strip-mine operators where the overburden is too thick to be removed economically. Large-diameter, spaced holes are drilled up to 200 ft (61 m) into the coalbed by an auger. Like a bit used for boring holes in wood, this consists of a cutting head with screwlike extensions. As the auger ...
