这里有一个美丽而奇妙的传说:相传很早很早以前,古同关北部有一青一黄两条巨龙沿西南向东北方向游荡,每条龙的嘴里都含着一颗宝珠。在飞越瑶曲上空时,青龙所含的宝珠不慎失落,便从天而降,因未寻到宝珠就在这里安了家,最终坐化成长蛇岭,从此以后,岭上一年四季葱葱绿绿。进入七十年代,青龙当年遗落的宝珠在岭下八百米深处被找了回来。这就是座落在长蛇岭脚下的陕西铜川矿务局下石节煤矿所生产的优质长焰煤。 Here is a beautiful and wonderful legend: According to legend, very early long ago, the ancient customs of the North with a blue dragon two dragons along the northeast to the southwestern direction, each dragon’s mouth contains a treasure.
