October 11. Seghill. Explosion in the yard coal seam. One man was so severely burnt that he died. When the collieries of Burradon and Seghill were in the hands of the Messrs. Carr, the ventilation was in common; the Seghill pit being the upcast not only for its own extensive workings in the low main seam, but also those in the yard coal, together with a portion of air from Burradon, the furnace smoke and the steam discharged from a large underground engine, the upcast shaft being only 8 feet diameter; the amount of ventilation in the yard coal was therefore limited to a few thousand feet per minute. Although a very small extent of workings and carrying on with naked lights, it came out during the inquest that upon a fall of the barometer, a great discharge of gas was emitted from a trouble which ran through the workings, and upon more than one occasion narrow escapes had taken place. Having thereupon examined the pit, and now that the ownership of the collieries is distinct, I caused them to be disunited in the ventilation by permanent stoppings, which has had the effect of placing both collieries in a most satisfactory state, each ventilating its own works independently.
