Seems to me they could smother the fire by covering the hole with a huge tarp ..........................

230 feet wide would be quite a tarp.

It’s over 1 1/2 acres. I don’t know of any tarp that they could secure air tight that way. The only thing I can think of them doing is to laydown metal slats across the hole until they have it covered. That’s assuming the hole isn’t burning at a temperature that is high enough to melt steel.

I think that they should cast the world's largest iron grate and then construct the world's largest teapot. Sorry Chester West Virginia.
