Circuit Diagnostics leading to pressure and leakage reduction

Dallas Mining Services specialise in diagnosing the health of the ventilation circuit.

This can be done by furnishing the following:

• A copy of the mine plan in a drafting or dxf format.
• (John Rowland is a qualified mining surveyor and will show the plan
• the confidentiality and respect it deserves)A current mine ventilation model where availableA copy of the mine monthly ventilation survey data.

The above in conjunction with some relevant questioning is normally sufficient to do an initial circuit assessment by assessing the major areas of leakage and high resistance.

The work list is then defined in order of priority to examine areas of excessive leakage.

Underground inspections and relevant measurements may be used to identify or substantiate suspected areas of high resistance and leakages.

The process result is improved face air quantities and efficiencies, lowered fan pressures and operating costs and extended ventilation system life.
