Lot of good coal left here. The top does look unstable, which is why I do not enter any of these mines but send my camera in on a 12 foot board (or in this case because the opening was so small, i just taped my camera onto the end of a shovel and slid the shovel into the opening--my camera sends a wifi signal back to my cell phone so I can see what the camera sees inside the opening).
unsupported top.... That looks like good coal.
