Dallas Mining Services has all the gear to conduct mine-wide pressure
quantity surveys at the clients request.
Surveys are
now done using both barometric (indirect) and the hose drag
(direct) method and we have 3 x Paroscientific Barometric
Standards,
600 metres of tube, electronic manometers and sufficient
anemometers, electronic and mercury hygrometers, etc to carry out the job.
A full or
partial Pressure/Quantity survey may be warranted if the model
is grossly out of date and inaccurate and it may be cheaper and
faster to start again and determine new relevant mine
resistances by such an approach.
Sometimes it may
be required where emergency escape conditions are critical.
Under such a
scenario specific flow directions and resultant contamination in
roadways may be paramount to successful safe escape strategies
and Ventsim may be of assistance here.
