19. Note:
20. •At least 50% of experiments should be performed on actual / cut-section / working models; the remainder may use demonstrations, simulation software or OEM videos.
21. •Industrial visit to at least one underground mine and one opencast mine is recommended.
22. •Practical Sessional (PS) — 50 marks: attendance, lab record, viva and continuous assessment. Practical End-Semester Exam (PE) — 50 marks: experiment performance, sketching and viva-voce.
