AKTU Mine Ventilation (BMN602) Syllabus PDF – B.Tech 3rd Year

Course Outcome: After the end of the course the student will be able to

1. Understand the occurrence of mine gases, dusts and methane drainage and be able to develop and explain control strategies.
2. Explain the principles and control of heat and humidity behaviour in underground airways.
3. Outline natural ventilation and explain its application in underground mines.
4. Apply the principles of mine fan selection in order to evaluate the selection and produce improved solutions. COS: Plan, design, and solve problems related to basic underground mine ventilation systems.
