Ventilation was initially by furnace at the bottom of the No. 2 upcast shaft. At the foot of the upcast shaft a furnace was kept continuously burning. The North (upcast) was and the South deep respectively. Ventilation was provided by a furnace near the upcast shaft on the Trencherbone seam. Stoves were installed at the bottom of upcast pipes to overcome the problem of ventilation. The induced draught was obtained from a pair of furnaces from the upcast shaft. Two main pits were sunk&colon; the North Shaft (downcast) and the South Shaft (upcast). One section was reserved for upcast ventilation provided by a furnace. All the dead were in the headways by William Pit (the upcast pit). The downcast shaft was converted to upcast with a furnace at its foot. Smoke was seen from the upcast pit and air came from number 2. The shaft was subsequently used as the upcast shaft by Wilson Wood Colliery. The colliery's two shafts were both deep, the downcast Lancaster and the upcast York. The upcast shaft was then fitted out for coal winding and output continued to climb. The upcast shaft was used for winding men and had a smaller horizontal winding engine.
