Denaby Pit to Close for Alterations.
Toward the end of next month the Montagu shaft at Denaby Main Colliery is to close, and over 500 workmen will be effected.
The winding engine which has been in constant use for 63 years, is to be demolished, and replaced by a modern type.
It is estimated that the work will not be completed under twelve weeks.
Arrangements are being made for the absorbing of the men by Denaby Deep or Cadeby Main.
