John Rowland at Dallas Mining Services has had considerable experience designing small auxiliary
ventilation systems for underground and surface mining,
industrial and environmental applications.
He has designed
numerous ducting and fan installations for projects including
extended single entry driveages, surface to underground long run
systems, blowing auxiliary systems and the like.
Installations
have been diverse and pictured is a series installation
utilising 2 x 23m3/sec auxiliary fans and an evasee to drive
extended distances in the absence of a primary ventilation
system.
Dallas Mining
has also developed a leaky duct Excel spreadsheet which involves
the use of a diverse database of fan curves which can be linked
to a circuit resistance under assessment and Ventsim is also
utilised as a suitable modelling tool for many applications.
Considerable
testing and application under real conditions has shown repeated
acceptable practical results when compared to modelled values.
Most of this
work can be done remotely from the site and relatively
inexpensively over extremely short time frames to satisfy the
client.
