Under the conceptual name “ventilation on demand” (VOD), research institutes and mining companies are designing new concepts for coping with these challenges regarding air quality, system optimisation and energy efficiency. Further on, today’s and possible future challenges are being discussed. This paper introduces past mine development as a motor for progress and describes historic challenges in ventilation with corresponding solutions. Until today, these trends are ongoing, meaning mines are still increasing in complexity, depth and machinery used, thus ventilation is facing new challenges. Ventilation was not only affected in terms of increased air quantities to be supplied, but controlling the airflow also gained attention. As mining activities advanced throughout the centuries, mines increased in depth and complexity, resulting in the development of new technologies and processes.
