The town at risk from cave-ins

In what sounds like the plot of a bad horror film, we read that "kids in Picher, Okla., are exposed to lead, and the ground is at risk of cave-ins" due to the "abandoned mines beneath the city."
Turns out the whole town is now under "voluntary buyout" by the US government because the place is so polluted that no one should be living there. Tailings from abandoned lead and zinc mines are to blame; indeed, there are "giant gray piles of mining waste, known locally as 'chat,' some hundreds of feet tall and acres wide, that loom over abandoned storefronts and empty lots."

From the Washington Post:

Signs of Picher's impending death are everywhere. Many stores along Highway 69, the town's main street, are empty, their windows coated with a layer of grime, virtually concealing the abandoned merchandise still on display. Trucks traveling along the highway are diverted around Picher for fear that the hollowed-out mines under the town would cause the streets to collapse under the weight of big rigs. (!) In some neighborhoods, empty mobile homes sit rusting in the sun, their windows broken, their doors yawning open, the detritus of life – car parts, broken toys, pieces of carpet, rotting sofas – strewn across their front yards.

But what happens in twenty years' time, when a group of joy-riding teenagers from across state lines find themselves driving through Picher in the late afternoon...? They park their car, laughing, and throw rocks through some windows; one of them sneaks behind the old neighborhood Piggly Wiggly and opens up the door of a small shed – finding the entrance to a mine... When, suddenly, the ground opens up on the main street and swallows all three of his friends.
He hears screaming – as well as what sound like whispering voices coming from beneath the ground all around him...
The sun is now setting. Swallowing fear, our naive hero of the high school football squad descends into the lead mines to find them...
Or has that film already been made?
