Learning Geology: October 2015 - Blogger
If geological studies identify a trap, and if the geologic history of the region indicates the presence of good source rocks and reservoir rocks, geologists make a recommendation to drill. (They do not make such recommendations lightly, as drilling a deep well may cost over $50 million.) Once the decision has been made, drillers go to work.

Mar 23, 2022When quarries are formed, back shattering from the blast and subsequent relaxation of the rock strata pose a considerable stability challenge. Not everyone can identify true dip in sedimentary rock, which would indicate the possibility of potential failure. The Stoney quarries (not Horseshit) are particularly vulnerable.

Gravel from natural, porous rock gives the soil heft and weight it needs while still allowing water to filter through easily. 3) Non-Absorbent Stone Most natural stones and rock types are absorbent because they're porous and allow liquids to sink through. Non-absorbent stone might seem counterintuitive in this light, but it has its use.

As said, they are drill cores for charges. But the reason they are so intact, I believe is because the charge is relatively small and they have drilled several cores along the fracture zone. The cores are to create a weakness in the rock and, a fracture is created between/along the cores, by the explosion and the block will fall down by itself due to good ol' fason gravity.
