There seems to be some confuson through the years which is which shaft, as the No1 and No 2 (filled) are located abot 100 yards from eachother. After further research the shaft that failed was the No 1. ( sorry Chris). This makes a big difference as you can tell from the profile. The No 1 is 773.4 feet deep. And reaches the Dunmore No 3 vein. The water pool lies at +600(winter) to +630 ASL ( spring) The shaft is 37. 5 feet in length, and 10.3 ft. in width. It consists of four compartments. From the SE to NW.
Compartment 1= pumpway 8.83 ft long
Compartment 2=hoistway 7.92. ft long
Compartment 3=hoistway 7.92 ft long
Compartment 4=airway 12.83 ft long.
