This issue of Mining Report Gl\u00fcckauf therefore examines developments in mine ventilation over the course of recent decades and discusses the current challenges and possibilities that exist in this particular field.<\/p>\n<p>The development of the mineral mining industry has always been characterised by an increase in the working depth, greater complexity in underground infrastructure and the introduction of new mining methods and technologies. This created a need not only to install underground ventilation systems in general but also to provide ever more effectively controlled ventilation in line with the demand for greater volumes of fresh air supplied to the workings.<\/p>\n<a href=\"http:\/\/2025.mining-report.de\/english\/current-issue-4-2017\/\" class=\"shortc-button small white\">Read more<\/a>\n<p>With my best regards \/\/ Mit freundlichem Gl\u00fcckauf<br \/>\nDipl.-Ing.

Main challenges and drivers have been the development of mining activities towards greater depths, more complex deposits with a larger areal extent, the further introduction and implementation of diesel-powered vehicles as well as stricter occupational exposure limits and rising energy costs. To meet these requirements and to keep the operation viable, new holistic ventilation concepts, methods and tools need to be developed for providing and guaranteeing sufficient fresh air for safe and efficient operations in underground mines at all times and all locations. Current approaches focus mainly on the development and implementation of ventilation on demand concepts (VOD) and systems. However, the smart and intelligent, safe \u201cMine of the Future\u201d demands the further development of advanced and adaptive ventilation systems.<\/p>\n<p><strong>Author:\u00a0<\/strong>Dr.-Ing.

Ventilation was not only affected in terms of increased air quantities to be supplied, but controlling the airflow also gained attention. Until today, these trends are ongoing, meaning mines are still increasing in complexity, depth and machinery used, thus ventilation is facing new challenges. This paper introduces past mine development as a motor for progress and describes historic challenges in ventilation with corresponding solutions. Further on, today\u2019s and possible future challenges are being discussed.<\/p>\n<p><strong>Authors:\u00a0<\/strong>Felix Dicks, cand. M.Sc. Mining Engineering, und Dr.-Ing.

Demand-oriented ventilation technology is based on the fundamental idea that those areas of the mine where a lot of work is being done should be provided with a greater flow of ventilation air, appropriate to their needs, that those parts where there is little or no activity whatsoever. In this way it is possible to increase the volume flow in the active production areas at the expense of the ventilating air that is delivered to the non-active zones. The aim is to achieve the optimum volume flow control at the lowest operating cost based on the minimum volume flow requirement in the areas concerned. This paper examines in detail the fundamental concept of ventilation on demand (VOD) and the basic approach that is being taken from today\u2019s perspective.<\/p>\n<p><strong>Authors:\u00a0<\/strong>Dr.-Ing.

When mine rescuers finally arrived, eleven of the twelve had died of CO poisoning. This prompted the US government to enact the MINER Act and follow-up regulation, requiring all underground coal mines to maintain mobile underground refuge chambers that provide life support for up to 96 h.<\/p>\n<p>This paper examines some of the engineering challenges associated with refuge chambers, including:<\/p>\n<ol>\n<li>the airlock function designed to keep toxic mine gases out of the chamber;<\/li>\n<li>the dissipation of metabolic heat generated by the occupants inside the chamber;<\/li>\n<li>the resistance to withstand fires and explosions;<\/li>\n<li>the difficulty of making accurate air quality measurements in a condensing atmosphere inside the chamber;<\/li>\n<li>the ability to communicate to the outside; and<\/li>\n<li>the decision to shelter and the psychological pressures for miners inside the chambers.<\/li>\n<\/ol>\n<p>The paper will provide an overview of current research and suggests improvements to overcome current limitations.<\/p>\n<p><strong>Author:\u00a0<\/strong>Prof. Dr.-Ing.
