While I may not be an engineer or a miner, my experience with digging has led me to make two important observations: First, whenever a hole is excavated, a pile of dirt, rocks, and debris is created nearby. This pile will be larger than the volume of the hole, at least initially. Second, since a man cannot stand inside a hole and dig simultaneously, the width of the hole increases in proportion to its depth. Consequently, deeper holes will have a wider opening at the surface, resulting in noticeable ground disturbance.

Considering these observations about excavation, if the hole beneath the pyramid is indeed miles deep, there should be a substantial amount of disturbed material nearby, or the surrounding area should be elevated if the excavated material is spread out evenly. Additionally, if the material were backfilled into the hole, we would expect to see a surface profile disrupted by rocks and debris, inconsistent with the surrounding desert landscape. I wonder if the archaeologists took these factors into account, as I didn't notice any evidence of this during my visit.
