Ventilation and Climate Control

Prof. Paluchamy B · IIT Kharagpur

Start with lecture 1 At NPTEL

About

The course “Ventilation and Climate Control” focuses on the principles and practices of controlling air quality, heat, and environmental conditions in underground mines. It covers psychrometry, human thermoregulation, heat, dust, gases in mines, air cooling systems, airflow mechanics, mine fans, and ventilation simulation and planning. Emphasis is placed on mine safety, statutory compliance, and energy-efficient ventilation design. The course combines fundamental theory with practical examples relevant to modern underground mining operations and emerging concepts such as ventilation optimisation and ventilation-on-demand.

Intended audience: UG Students

Prerequisites: Students are expected to have completed basic undergraduate-level courses in Engineering Mathematics and introductory Mining Engineering subjects. Prior exposure to Fluid Mechanics, Thermodynamics, and Underground Mining Methods will be advantageous; however, it is not compulsory, as the necessary fundamentals will be introduced within the course.
