Maybe old mines should be filled so that it will be hard for Zama Zamas to go in

Builders foam

Like that would stop them, you can also just pump the old mine heaps back into the shafts, the ground water is already contaminated.

I guess if possible I would pump oodles of foam in and then use 100 foot quick dry cement and reinforcing at the entrances.

Wasn't a serious response but now I'm wondering: even if it doesn't stop them it would delay them especially if you keep on refilling it.

Logistics, costs, scale and environmental impact aside...

+- 2000 liters covers about 16000 square feet, it comes in plastic bags as well, simply shake the bag about, cut it open and pour.
