Digging Deepest Hole In World Is A Boring Job
The world’s deepest hole near Fort Stanton New Mexico reaches 15,270 ft after years of work. It prints 200 times air pressure at the bottom and rocks crumble easily. A 20 inch top pipe narrows to 7 3 4 inches as crude oil rises in a five inch return line. Cement surrounds the lower pipe to anchor it in sand rock and a 30 foot gun with steel jacketed cartridges penetrates the area to allow entry.
