The Davy lamp helped canaries because it was a safety lamp used in coal mines to detect the presence of dangerous gases like carbon monoxide. Canaries are sensitive to these gases, so if the bird showed signs of distress or illness, miners would know to evacuate the mine to avoid danger.
Rocks fall onto your head, and in low seam coal, you hit your head on the roof (last mine I was in was only 48" high) It also gives you a good place to attach your miner's lamp, so you can see what you are doing.
Humphry Davy invented the miners lamp to improve safety for miners working underground. The lamp, known as the Davy lamp, reduced the risk of explosions caused by flammable gases such as methane that were present in mines. It provided a safe source of light without igniting these gases.
