Decreasing of the air humidity by the ventilation control in the St. Barbara mine

The St. Barbara mine is a visitor having large amount of timbering support which deteriorating fast due to the high humidity conditions. air conditioning system mining not suitable and also expensive for implementation in shallow non-productive mine. As there are no usual contaminants mines, ventilation could be powered only when dew point outside below strata temperature. Applying this rule would certainly avoid condensation, but raises potential partial dehumidification walls as moisture can evaporate these A microclimate analysis, based on one-year data, has showed that favorable conditions occur through major part year. Their availability mostly 100%, during summertime periods it drops down 13%. real time monitoring with programable microcontroller allows automatic control adjustment psychrometric
