The thing about deep open holes is that heavy gases collect in them over time and the lighter oxygen floats out. A hole full of dirt has no air in it and as you take the dirt out the oxygen and normal atmosphere come into the hole with you as you remove the dirt. Also the motion of a bucket moving in and out of the hole a few times a minute causes a lot of air circulation. I have dug hundreds of deep brickliners and bad air is not a problem with holes that you are removing dirt out of.
Now digging a hole down many feet and leaving it open over night could be enough time for the heaver gases to collect. And create a poisonous atmosphere in the bottom of the hole. One of the reasons i like to finish a hole the same day i start it even if it takes 24 hours of straight digging.
Holes that have been left open and capped off with concrete or stone can be very dangerous as these will most defiantly have poisonous gasses in the bottom. Always ventilate any open pits or have proper breathing gear before entering these types of holes.
