Louisiana Grills LG900 Review Update
In mine the pellet feed did not run as the temp dropped from 400* to 235* and flipping it into the "off" shutdown mode stops my auger from advancing anymore but lets the fan run until my temp is 130* and then shuts everything off. I'm catching the temp drop before it hits 200* and the auger starts to feed pellets again the way I do it.

What Is An Auger, And What Are They Typically Used For?
Share. Simply put, an auger is a spiral-shaped tool that is used to drill holes into the ground and other surfaces or materials. The spiraling metal shaft with a blade at the end of the device is known as a "flighting". The flighting rotates to scrape, cut, or siphon out drilled materials.

serves from a surface mine when removal of overburden with sur- face mining equipment becomes uneconomical. Auger and con- tinuous miner head machines are the two major types of equip- ment used in U. S. highwall mining. The auger type machines use a horizontal auger to literally drill coal from under the highwall in a series of parallel holes.

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.

The Assay Explains Surface Mining
Auger mining refers to mining coal at a high wall or cliff by drilling holes into an unprotected coal mineral seam and transporting it along an auger bit to the surface. High wall mining is a remotely controlled mining process that isolates coal from the base of an exposed high wall. The technique has a low capital cost and less production time ...

Introduction to Mining | SpringerLink
1.5.6 Auger Mining. Auger mining refers to a method of removing coal, clay, phosphate, oil-shale, etc. from thin seams exposed in deep trenches or high-walls in strip mines. The auger consists of two principal pieces. The first is a cutting head, generally from 1.5 to 8 feet in diameter. It may be single or multiple.
Coal Augering Services
Auger mining operations drill a series of parallel holes perpendicular to the highwall, leaving adequately sized pillars between holes to maintain the stability of the highwall and overlying surface area. The technique is also commonly used to recover coal beneath surface features which limit surface mining, such as rivers and roads.
