What is "poolsbrook"

Poolsbrook is a former mining village near Staveley (where the population is included) in North East Derbyshire, England. The village was built by Staveley Coal and Iron Company towards the end of the 19th century to provide housing for workers employed at the nearby Speedwell and the later Ireland Collieries. Since then new houses have been built (dubbed the "new village" by locals) and the old house have been knocked down.
