Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, in particular to a safety helmet for mining operations. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. A mine mainly includes one or more mining workshops (or pits, mine shafts, open pits, etc.) and some auxiliary workshops. Since the mine is deep underground, the air content and light inside are seriously insufficient, and the mining of the mine is likely to cause changes in the mountain structure and cause landslides. Therefore, in order to protect the workers, they must wear corresponding safety helmets.

[0003] At present, the mining environment is generally hot and humid. It is difficult to discharge the hot gas only by relying on the ventilation holes on the safety helmet. The high heat dissipation of the head and the low ventilation rate of the safety helmet will form a high-temperature and humid microclimate environment between the head and the safety helmet, causing the heads of people who wear safety helmets for a long time to be hot and airtight, causing discomfort to the workers, which will affect their central nervous system and cause a decrease in muscle working ability, attention, movement accuracy, coordination and reaction speed. It will not only affect the improvement of work efficiency, but may even easily cause work accidents and endanger the health of miners.

[0004] A kind of safety helmet for mine operation is proposed for this reason. Utility Model Content
