Carbon monoxide? It can't all be clear, or the rescuers would have walked down the shaft.Lesleegp said:I just saw a clip of the entrance of the mine. It does seem to have some type of concrete framing around the entrance. Otherwise it's all muddy.
Also from my understanding, there was no cave in anywhere along the mine shaft. Makes me wonder why the miners didn't make their way back up the shaft. Easy to Monday morning quarterback......so many what if's.....
