Environment and conditions

 

        The current maximum depth of the mine is 1444m.

 

    Visiting hours are every day from 5 am – 22 pm.

 

    Good air quality is ensured via a continuous and maintained fresh air supply from above ground.

 

       The humidity and temperature vary from level to level. The maximum temperature at the main level (1410) is 25 degrees Celsius. Humidity between levels can range from 50-100%. It is important to note however, that the temperature and humidity at a certain level stays stable.

 

     To facilitate safe passage around the mine via tunnels, driving routes are maintained daily.

 

    The main level, tunnels, and research facilities are fortified by rockbolts, iron netting, and shotcrete.

 

    Microseismic monitoring, as well as real-time monitoring and warning of harmful gases, are the key in providing a safe environment for all.

 

 

 

 

 

 

Haapaveden biojalostamo ja Pyhäjärven kaivoksen pumppuvoimala suurimmat energiatuen hakijat. Energiatukea on haettu 140 miljoonan euron edestä ja sitä myönnetään 40 miljoonaa. #CallioPyhajarvi #PPHES #EnergyStorage #InvestFinland #PyhasalmiMine maaseuduntulevaisuus.fi/talous/artikke…

Pyhäsalmen tyhjentyvässä kaivoksessa testataan tulevaisuuden ruokatuotantoa, joka voisi toimia myös Marsin laavatunneleissa suljetun ruoantuotannon steriilinä kasvatusympäristönä. #CallioPyhajarvi #PyhasalmiMine #EdibleInsectsFromMine #kiertotalous bit.ly/2xzM4Uy

Worth of reading. The highest IRR of #PPHES @CallioPyhajarvi can be achieved with a combination of a 50 MW turbine, 62.5 MW pump and 500 MWh reservoir. The IRR of the optimal investment varies between 10.46 and 10.65%. #PyhasalmiMine #InvestEU #InvestFinland #EnergyStorage twitter.com/HuukiHannu/sta…

Pyhäsalmen kaivoksen ainutlaatuista infraa hyödyntävä palo-, pelastus- ja suojelualan koulutuskeskus on toteutumassa. Underground Rescue hanke on saanut tänään positiivisen rahoituspäätöksen. #CallioPyhajarvi #UndergroundRescue #PyhasalmiMine #ppliitto callio.info/2017/wp-conten… pic.twitter.com/rovuNywK7R

What do you expect to see at the depth of 1.5 km? Physicists filling the #underground Lab 2 of @CallioPyhajarvi with their instruments. The research is done as a part of @BalticRegBSUIN project. #BSUIN @UniOulu @uniofjyvaskyla @baltic_sea_prog @Moedas #interreg #BSR #BSI pic.twitter.com/HIaGPiZ6OV Retweeted by Callio Lab
