(2) Strictly harmful gas detection system and anti-radiation measures Develop technical measures for discharging and diluting harmful gases, strictly control harmful gas, and limit the content of harmful gases such as sulfur dioxide and carbon monoxide in the construction site to within the specified range. Special protective measures such as shielding and dilution should be strictly applied to work with radiation hazards.
(III) Comprehensive preventive measures for pneumoconiosis and sand lung disease Mainly through the five aspects of wind, water, dense, clean and protective, comprehensive dust prevention, mainly wind and water. Wind is ventilation and dust removal; water refers to wet operation; dense is closed dust; net is purified air; protection is to take personal protective measures for workers exposed to dust.
(IV) Personal protective measures Personal protective measures include consciously abide by safety regulations, adhere to personal protective work, and master personal emergency handling methods.
(I) Improvement of high-temperature working environment In the underground construction of mines, ventilation and cooling measures are mainly used. The first is to determine the ventilation method and related parameters according to the number of working faces; when the ambient temperature is high, it can increase the ventilation and increase the wind speed. When the ventilation does not meet the cooling requirements, local mechanical cooling measures can be taken to cool down. For work with heat damage or heat radiation, the construction process should be reasonably designed, and automated and mechanized construction methods should be adopted as much as possible to avoid or reduce contact with fire and heat sources, and the impact of high temperature and heat radiation on the operators.
