Not sure what is happening here. Certainly, no drilling action is being conducted. It appears to me they are using the skinny guy for retrieving a tool or something. His clothes are not soiled enough to have been excavating a bell at the bottom of the bore hole. Maybe the object he brought up by his feet was what he used to inspect the undercut diameter at the bottom.
