相传很久以前，从天外飞来一只金凤凰，她闪耀金光，抖动金翅，将口中一块“太阳石”洒落在冀东平原上。后来，在凤凰落脚的地方耸立起一座秀丽山峰──凤凰山；在凤凰山脚下，那块神奇的“太阳石”化作了８９０平方公里的富庶煤田──开滦煤田。 开滦煤矿建于 １９世纪 ７０年 According to legend, a long time ago, flying a golden phoenix from outside the sky, she flashed golden light, dithered gold wings, and sprinkled a “sun stone” in the mouth on the eastern plains. Later, at the foot of the phoenix, a beautiful mountain peak, Fenghuang Mountain, was erected. At the foot of the Phoenix Mountain, the magical “sun stone” turned into a 890 square kilometer-long coalfield, the Kailuan coal field. Kailuan Coal Mine was built in the 1700s
