Not illustrated. 1861 edition. Excerpt: ...of the East Minor Pit, which was a benefit to the West Minor Pit. What the Eppleton Pit upcast took was a benefit to the West Minor Pit. At the time of the explosion I think we would have 157,668 cubic feet per minute going down. That was measured a fortnight before the explosion. It does not surprise me, with that quantity of air, that there has been so much after-damp from the explosion. I know, of my own knowledge, that men have been suffocated, at considerable distances, in all directions from the shaft. I have travelled some distance underneath after-damp, but not a considerable distance. The furnaces, after the explosion, did not assist to make after-damp. The burning of the hay in the stables I think would. It made a serious quantity of smoke. I do not think any man could have lived where it was very strong for any length of time. I believe there has been no other gas, except what was in the flue, to cause this explosion. There was no possibility of gas getting from the Low Main to the flues, because the flues were shut off altogether, and it could only get through the damper, and would have to pass over the fire, and, although damped, would have exploded, and gone back to the Low Main. Gas generated in the Low Main would make for the upcast. If gas came down the downcast shaft, and so over the fire, it was impossible for it to get into the flues. If it did, it would pass No. 1 and No. 2 boilers before it came to the flues. No. 3 boiler has flues: the others have none. I do not think it possible for any gas to come down the downcast, from the quantity of air we had. There was no goaf to foul from in the east, and the returns were examined in the west, and no gas found. I think it is possible, with so large a quantity of air, when the...
