SHORT COURSES

Level: Intermediate

Facilitators: Tim Paquin, BBA & Marc Seewald, ZITRON

This workshop will prove to be beneficial for anyone involved in ventilation systems from the consultant to mine ventilation personnel to mine operations workers.

In this workshop the participants will explore:

• Does your mine use diesel or BEV equipment?

• How to determine mine airflow requirements?

• How to arrive at a fan duty point?

• Should my ventilation design be a push or pull system... and why?

• How to optimize the primary fan installation location (surface or underground)

• What information does the fan vendor require?

• Definitions/Pressure

• What are system losses?

• What are system effects?

• How to read a fan curve?

• Why a basic understanding of the fan laws is important?

• The role of OPEX vs CAPEX in fan selection

• Fan stall- The danger of a bad selection

• Auxiliary Fan Selection

• Auxiliary Duct Selection

• Not all fans are created equally

• Testing Tolerances- Site vs Factory Testing

• Useful formulae

Short Course Objectives:

In this workshop participants will learn, and have the opportunity to discuss, how to determine airflow requirements and fan sizing whether at their mine site or for mining study purposes. The workshop will use a systematic step-by-step approach which will allow participants to start from A and work their way through to Z. The workshop will touch on several ventilation aspects which will ultimately enable the participant to select a primary or auxiliary fan system.

Content will answer questions such as:

• What is a duty point?

• What are system losses?

• How to size an auxiliary system?

• What is a hybrid mobile equipment system?

• How to write a fan specification?

• Fans laws and their importance in system design?

• What are the usual formulae and their applications?

• I have lots of auxiliary fans at my mine site, aren’t all 50 hp fans the same?

Participants will leave this workshop with more applicable tools and best-practice information on mine ventilation and fan selection, making themselves more confident when encountering these questions in their jobs.

Target Audience:

The target audience for this short course will be any ventilation personnel, from technicians to engineers, whether located in operations, consultancies, or academia.

About the instructors:

Tim, L.E.L., is a Senior Ventilation Consultant, who has been working in mine ventilation for over 35 years. Of that time nearly 30 years has been in consulting and 8 years in mine operational experience prior to that. Tim brings a hands-on, knowledge based, practical approach to mine ventilation design and planning. His experience spans designing, evaluating, and advising on new and existing systems worldwide.

Marc, P. Eng. is a Senior Mechanical Engineer, who has been working in fan and ventilation plant design/analysis for 13 years.
