Safety lamp could create a sufficient updraft that firedamp would not penetrate down the chimney. Further observations of the speed of flame fronts in fissures and passageways led him to design a lamp with fine tubes admitting the air. Sir Humphry Davy was asked to consider the problems of a safety lamp following the Felling explosion. Previous experimenters had used coal gas (chiefly carbon monoxide) incorrectly, believing it to be the same as firedamp. Davy however performed his experiments with samples of firedamp collected from pits. As an experimental chemist, he was familiar with flames not passing through gauze; his experiments enabled
Durham Miners Heritage Centre Durham Miners Heritage Centre The Durham Miners Heritage Centre was a museum, now closed, run by the Durham Miners Heritage Group at Neville's Cross, Durham, England. It had a display of coal mining memorabilia and an exhibition of art. One of the main reasons for the display was to educate the next generation of children about the mining past of County Durham and to give opportunities to research coal mining history, especially local school groups in the area and visitors to the city. The displays included mining pit lamps such as the famous Davy lamp, tools used in the mining
