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
more frequent)
