A HISTORY OF DURHAM 



Boring operations from the surface were in 

 progress at Shincliffe Colliery, near Durham ; a 

 bore-hole was put down from the surface a 

 quarter of a mile south of Hartbushes Farm

 face to the Main Coal Seam. 



A sinking was commenced on 21 January and 

 put down from the surface to the Five Quarters

 to the Main Coal, as soon as the pump and 

 engines were set to work, about 1 1 fathoms 

 further. 



Belmont Colliery Furnace Pit sunk. 



The Big Pit, White Lee Colliery, was put 

 down from the surface to the Main Coal Seam,

1 84 1. — Brancepeth Park Colliery was sunk 

 from the surface to supposed Harvey Seam. 



Framwellgate Moor Colliery was completed. 

 This sinking was remarkable for the great amount 

 of piling employed to carry the shaft through 

 alluvial strata 1 20 ft. in depth. The excavation 

 was commenced at the surface with a diameter 

 of 30 ft., which, by the introduction of succes- 

 sive tiers of piles, was reduced to 14^ ft. diameter 

 at the stone head.^' 



Westerton Colliery commenced shipping coal. 



Whitworth Park Colliery was won to the Hut- 

 ton Seam at a depth of 516 ft. and at a cost of 

 j^40,ooo by the Durham County Coal Company. 



Coal was won at North Biddick Colliery. 



Sinking was commenced at Harton Colliery, 

 10 May, and on 10 July, 1844, the Bensham 

 Seam was sunk through at a depth of 1,290 ft., 

 being the greatest depth reached in the Tyne 

 district. The shaft was a single one and divided 

 into two by a timber brattice, and is remarkable 

 for the cast-iron tubbing required, which extends 

 to a length of 474 ft. owing to a fault met with 

 in the shaft in sinking. 



Owing to this fault, one of the sinking sets 

 reached the abnormal length of 474 ft. The 

 royalty was of unusual magnitude, comprising 

 an area of 9,000 acres, being the most extensive 

 in the trade.
