What Must Be Monitored for Each Underground Coal Mine Meeting the MSHA Sampling
Threshold?

   Each underground coal mine meeting the MSHA threshold must monitor
               these parameters for their mine ventilation air ...
Volumetric flow rate of gas for each
ventilation monitoring point (scfm)
(Quarterly or more frequent)
                                                Pressure (arm) values at the time,
                                                location, and conditions for which
                                                measurements are made. (Quarterly or
                                                more frequent)
CH4 concentration (%) for each
ventilation monitoring point (Quarterly
or more frequent)
       Temperatures (R) values at the time,
       location, and conditions for which
       measurements are made. (Quarterly or
       more frequent)
                                                Moisture content (%) at the time,
                                                location, and conditions for which
                                                measurements are made. (Quarterly or
                                                more frequent)
 Each underground coal mine using a degasification system (deployed before,
  during, or after mining operations) must also monitor these parameters...
                                         Pressure (arm) values at the time,
                                         location, and conditions for which
                                         measurements are made. (Weekly or
                                         more frequent)
       Volumetric flow of QrU liberated from
       each degasification monitoring point
       (Weekly or more frequent)


       CH4 concentration from each
       degasification monitoring point (%)
       (Weekly or more frequent)


       Temperatures (R) values at the time,
       location, and conditions for which
       measurements are made. (Weekly or
       more frequent)
                                         Moisture content (%) at the time,
                                         location, and conditions for which
                                         measurements are made. (Weekly or
