RE: in conclusionSorry likesit but the augers are digging sideways into the seam and not downwards!!! The augers are capable of going in 30 meters.
That is about 100 feet into the side of the seams.
Exerpt: "The augers are capable of being fitted with various size boring heads to accommodate fluctuations in coal seam thickness and are capable of penetrating to a horizontal depth of more than 30 meters into the coal seam.
BTW your math is really bad.
500 tons=500 x 2000= 1,000,000 (1 million lbs) divided bt 84 lbs per cubic foot = 11,904.76 cubic feet and not 20,000
Going on the high side of Nag's proposals of 10,000 tons:
3 feet x 3.14 (pi) = 9.14 cubic feet.x 100 feet = 942 cubic feet per 100 ft hole. 942 x 84= 79,128 lbs per hole.
That is aprox 39.5 tons per hole. 5000 tons per auger = aprox 126.5 holes/ month. On a work month of 22 days this would work out to around 5.7 holes per day. Remember these are only rough numbers as actual production numbers can and will vary.
You are really trying hard to try and make is sound that Nag's numbers are impossible to achieve. It seems that you do not understand the mining process they are doing. Either that or try a different attempt to spread doubt.
Now it's your turn here's a simple question for you...What is Blue Gem coal what sets it apart from typical coal, how old is it and how did the deposits end up in Kentucky???
