Transcribed by ear from here. If you still have trouble with the lyrics, the original, by Ivan Lee Meece (click) is much easier to understand, but more of a country song rather than bluegrass.

MINER'S LADY
(Ivan Lee Meece)

She welcomes him with open arms to a valley lush and wild
Her cabin is her castle, and Southern is her style
She's hell on wheels a-booming across the mountainside
A barefoot country woman, a snow-white Persian bride

CHORUS:
She's tall like a pine, pretty like a flower
Gentle woman, country cooking folks are fine
Dancing woman, banjo ringing through the pines
Lonely woman, til the miner's lantern softly shines

She rocks her baby tenderly in the midnight of a storm
When all she ever longs for is a man to keep her warm
But fire burns in her body from the mines down below
Down where her love is digging in the jet-black diamond coal

CHORUS (x2)

Banjo ringing through the pines

This is a transcription of the J. D. Crowe version. The original version by Meece does not have the line "She's hell on wheels a-booming..." instead singing "She's a miner's rock of ages upon the mountainside"
