Abstract

The invention discloses a mining safety helmet with a dustproof effect. The mining safety helmet comprises a filter element layer, a dustproof mask and a mining safety helmet body. The filter element layer comprises a moist sponge filter element, a waterproof cloth layer and an ABS plastic frame, and the dustproof mask comprises a mask body, a cotton surrounding edge and a high-elasticity silica gel plastic soft belt. The using method comprises the following steps that during underground operation, the mask is taken down from the position above the tongue of the safety helmet and put on the mouth and the nose. According to the device, the face load of a common dustproof mask to an operator can be greatly reduced, and operation is convenient; and compared with a common dust mask, the dust mask added with a filtration distance for a dust - containing gas to get into the respiratory system has the advantage that the inhaled rate of dust can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of coal mine safety production, and in particular relates to a mine safety helmet with dustproof effect. Background technique [0002] Coal miners are equipped with many labor protection products, such as mining safety helmets, dust masks, protective clothing, etc., among which mining safety helmets are the most important and compulsory labor protection products. Dust masks are also must-wear protective equipment for front-line miners. Excavation of waterways and mining of working faces will generate a large amount of dust. Wearing a dust mask can effectively reduce the dust in the air from entering the human respiratory organs, thereby protecting life safety. [0003] When the staff is carrying out excavation and mining operations, they often remove the dust masks due to the large size, heavy weight, and inconspicuous dust-proof effect of ordinary dust masks, which affect normal operations, causing dust to enter the...
