Deadly Colorado blaze renews focus on underground coal fires
2022年1月30日DENVER (AP) — A fire raging in an underground Colorado coal field in 1883 sent so much smoke pouring from cracks in the ground that the scene was likened to burning volcanoes and the state’s first mining inspector deemed the blaze “impossible to extinguish.”. Nearly 140 years later two fires still smolder in the now-abandoned coal field
