Why do coal miners use battery powered lamps rather than candle light lanterns to provide light inside the tunnels?
Coal miners use battery-powered lamps because they are safer and more reliable than candle lanterns. Battery-powered lamps produce a steady and bright light without the risk of open flames, which can ignite pockets of flammable gases in the mine. Additionally, battery-powered lamps are more durable and last longer than candles, making them more suitable for the harsh conditions of the mining environment.
