Excerpt from On Recent Improvements in Winding Machinery
The tendency of pits is to become deeper, and of the quantities of coal drawn to become larger and, therefore, winding machinery is of continually increasing importance, and is for ever being perfected.
It is attracting particular attention in the Charleroi coal field, where coal getting is now being carried on at a depth of 700 and even of 800 metres (765 to 875 yards.)
