Pre-requisites: Unit 21281 - Test for gases, interpret findings, and demonstrate knowledge of follow-up actions in an underground coal mine.
NZQA Unit Standard 7145: Design and maintain effective ventilation systems for an underground coal mine – Level 5, 20 Credits
Learning Objectives:
- Explain the principles and practices of ventilation in an underground coal mine.
