06.02.2020Ventilation networks of coal mines are extensive and very complex. Mines lead to less face advance rate during the release of methane. Therefore, there may be even a dozen or so longwall panels in such mines, but most often number does not exceed a few panels. Total airflow rate in the mines reaches up to a few thousands of cubic metres per minute.

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.

As you are aware that DGMS has started conducting Competency examination on the pattern of Computer Based Online Test (CBOT) with multiple choice questions (MCQs) for Mine Ventilation, Explosives, Fires and Inundation for First Class Manager's certificate of competency under Coal Mines Regulation(CMR), you need to be at par with your skill sets to qualify one of most competitive exam
Open fire in a mine gallery causes large-scale damage to property and sometimes precious lives. Such fires produce two distinct effects, the throttle effect and the buoyancy effect. These effects disturb the ventilation system of the mine. To understand the complex dynamic phenomenon of open fire and its effect on ventilation systems, a mine fire
mines simply did not encounter problem gasses as densely as coal mines did, and so the methods described by Agricola did not translate into the carbonaceous setting.5 By the beginning of the nineteenth century two methods were commonly used to ventilate coal mines, natural ventilation and furnaces.
Drawing of the layout of a coal pit. Henry Power's paper on experiments in mines and the ventilation of mines was read at the meeting on 3 December 1662. This was subsequently printed in Power's Experimental philosophy, in three books containing new experiments microscopical, mercurial, magnetical (1664). Copied from RBO/2i/049.
This project investigates mine ventilation and explosion prevention in underground coal mines. Such explosions are a major safety hazard for miners. We work between Mining and Mechanical Engineering. The work involves mine ventilation, explosion prevention, remote control, 3-D printing, motorized mining equipment at model scale.

The state of the mine ventilation needs to be monitored to ensure that the quantity of air is maintained consistently and that emitted gas levels are maintained below safe threshold levels. Monitoring is done both manually and by the use of continuously operating monitors that may indicate remotely, often to the surface. Ventilation; Coal Transport
