THE DEFINITIVE GUIDE TO GEOLOGICAL SURVEY

If mud cake just isn't formed appropriately → water from mud goes in → water comes in contact with clay/shale → hydration → so size improves → but there's no space to support this: bodyweight cannot be supported and this bulge breaks from inside of → slowly and gradually this caving retains on raising.

The subsurface water level is set by way of a hydrogeological survey, important before borewell excavation to assess water high quality and amount at certain spots. DTH needs a small amount of rotational torque to chop rock that also allows the hammer to drill straight. screening underground water to get a borewell usually requires a pumping exam
