Dogs are curious animals, particularly over anything freshly dug or burried. Well, he started digging at these mounds of dirt with cables. There were hundreds of them all in linear patterns. After pulling and pulling, I pulled out a "Blasting Cap". Well it turns out the best way to make a backhoe's job a lot easier to dig about 500, 50' X 50' X 20' deep basement foundations was to blast it all to hell and turn the rock to gravel.
Why not just bury explosive charges about 30' down about every 100 feet and just set off the charges? Every tunnel, cave, void, etc.... will just collapse.
I read this the other day ...

Uncovering Gazan tunnel routes is critical, says prominent geologist and defense expert

Langotsky said the tunnels are being dug in a very professional manner, and the hundreds of tunnels that run under the Gaza Strip don’t seem to pose any threat of land collapse.
“The Hamas are very professional in the tunneling business...”
he warned. “Whatever they are doing is very impressive.”
“I tried to emphasize that we are talking about a longterm threat, not a short-term threat,” he said. Not only is the threat long-term; it is longrange in terms of geography, with possible tunnel threats along the Egyptian and Lebanese borders.
Before becoming capable of destroying these tunnels, the Israeli security system first needs to discover their locations and routes, he said.
