angel tunnelThe method of mining to be used by NAG in the North American Gem Mine #1 is known as contour mining. This type of mining is done on properties that were previously mined prior to the enactment of the Surface Mine Control and Reclamation act of 1977. This law requires that after any surface mining, the land must be restored to approximate original contour unless otherwise specified in the permit application and approved by the Kentucky Department of Natural Resources (KDNR). When "pre-law" mining was done, the general practice was to mine along the contour of a slope to the maximum profitable ratio and leave the resulting highwall and a wide, flat bench where the material covering the coal was removed and then graded somewhat flat as opposed to restoring the original slope.
The North American Gem Mine #1 is permitted for the use of augers to enter the coal seam from the exposed wall with minimal additional excavation and maximum cost effectiveness
.Key word here angel tunnel.
EXPOSED WALL. Now if your not in a tunnel your on the suface aren't you.
If a hole in a wall by a auger means tunnel to you then so be it.
Sometimes guys call it the tunnel too. lol
I'll try and learn more about minning now that i have to run this project. I thought i just bought shares and they would know how to get the coal out.
Cheers from the surface to the space between your ears.
