"Well, you see, sir, we put some gun-cotton in a small canister, with a fuse cut to last fowr minutes, and hid it in one of the old workings the men had left; then they telt t' overseer they thowt t' water was coming in by quickly. He got there just in time; and what with t' explosion, fire-damp, and fallen coal, we never saw t' over-seer again." "Dear me," said Monckton, "and Mr.
It is always bubbling out from the coal, and at any moment a pickaxe may break into a hole that is full of it. One kind of gas is called "choke-damp," because it chokes or suffocates any one who breathes it. There is also "white-damp," the gas which you see burning with a pretty blue flame over a hot coal fire. Worst of all is the "fire-damp."
In our day multitudes of people fall victims to all kinds of dreadful disasters, explosions of boilers, explosions of fire-damp, of everything that can explode, for the agents of destruction seem to be in a state of unnatural excitement as well as human beings. Never before, perhaps, have inanimate things seemed so much in accordance with the spirit of the times.
Of course, when Amedee appeared, the conversation was immediately changed, and they began to talk of insignificant things that they had read in the journals; for example, the fire-damp, which had killed twenty-five working-men in a mine, in a department of the north; or of the shipwreck of a transatlantic steamer in which everything was lost, with one hundred and fifty passengers and forty sailors events of no importance, we must admit, if one compares them to the recent discovery made by the poet inquisitors of two incorrect phrases and five weak rhymes in their comrade's work.
With between 11 and 12 per cent. of fire-damp the mixture was most dangerous. Pure fire-damp itself, therefore, is not dangerous, so that when a small quantity enters the gauze which surrounds the Davy lamp, it simply burns with its characteristic blue flame, but at the same time gives the miner due notice of the danger which he was running.
He had nearly reached the summit of the heap, when the fire-damp, which had accumulated in the hollow of the roof, exploded, and instantly the whole party were blown down, and the lights extinguished. They were a mile from the shaft, and quite in the dark.
The result of his thought was the apparatus still affectionately known to the pitmen as "the Geordie lamp." It is a lamp so constructed that the flame cannot pass out into the air outside, and so cause explosions in the dangerous fire-damp which is always liable to occur abundantly in the galleries of coal mines.
According to Simon Ford, the fire-damp escaped incessantly, and from that fact the existence of an important vein might be considered certain. Consequently, the riches of the Dochart pit were not entirely exhausted. The chief question now was, whether this was merely a vein which would yield comparatively little, or a bed occupying a large extent.
Explosions of fire-damp were unusually frequent in the coal mines of Northumberland and Durham about the time when George Stephenson was engaged in the construction of his first locomotives. These explosions were often attended with fearful loss of life and dreadful suffering to the workpeople.
W.E. Garforth, of Normanton, has introduced an ingenious invention, the object of which is to detect fire-damp in collieries with the least possible degree of risk to those engaged in the work. Mr.
