PROCEDURE FOR THE EVALUATION OF THE SAFETY PARAMETERS WITH THE HELP OF THE AUTOMATIC CONTROL OF UNDERGROUND ATMOSPHERE.

In accordance with the occupational health and safety standards currently in force, the safety parameters that define the underground atmosphere (mainly temperature and gases) will be monitored during the closing of mines, both during the proper closing and the preservation stage, as well during the temporary or permanent closing of the mine areas damaged during the mining period. The solution intends to warn against the hazards of undergrounds fires and gas and powders explosions; it consists in the automatic sampling and processing of information on the evolution of temperature and gases inside goofs and closed underground areas.
