Miner’slamp is an essential lighting tool for coal mine workers, the quality of its merits directly related to the labor productivity of coal mines and the safety of workers. At present, China has an annual output of nearly one hundred thousand sets of acidic miner’s lamp and alkaline miner’s lamp.
