Description

Technical Field

[0001] The utility model relates to a safety helmet, in particular to an air-purifying mine safety helmet. Background Art

[0002] Metal mines refer to places or facilities where metal ores are mined. Metal mines extract metal ores through underground or open-pit mining, and then go through ore crushing, grinding, beneficiation and other process steps to finally obtain high-grade raw metal mineral products for smelting. Metal mines can include the mining of a variety of metal ores, such as iron ore, copper ore, aluminum ore, zinc ore, lead ore, etc. These metal ores are important raw materials in industrial production and are used to manufacture various metal products, such as steel, wires and cables, and auto parts.

[0003] Metal mining is usually divided into two methods: underground mining and open-pit mining. Underground mining refers to taking ore out of the ground by digging and building underground tunnels and mines. Open-pit mining refers to removing the covering on the surface of the mine and obtaining ore directly from the open air. When mining ore, workers are required to wear safety helmets.
