Chapter 1: Mine Ventilation – An Overview Page 2 Revolution, the working of seams rich in methane gas, inadequate ventilation, furnaces located in methane-laden return air and the open flames of candles. There are many graphic descriptions of methane and coal dust explosions, the suffering of mining communities, the heroism of rescue at-File Size: 24KB. Les Gutzwiller(*) expounds on the advantages of centrifugal fans for longwall ventilation, and for use in coal preparation plants Mining practices and the industry's fan application problems have changed dramatically over the last 70 years or so since J.R. Robinson authored a technical volume entitled Practical Mine Ventilation in In coal-mine ventilation problems the works of Atkinson and Murgue have been the standard guide for many years. Later compilations have been made, such as that of Fitch. However, though most of the experiments of these authorities were carefully conducted, . Ventilation. Good quality air has to be provided for personnel to breath, to dilute both natural and introduced (e.g. diesel exhaust) gases, to dilute or carry away .

  This MSHA film clip demonstrates various ventilation techniques to control dust including the use of proper face ventilation to effectively remove airborne dust. Over the years, some. Fig Ventilation network model/diagram of small coal mine (VnetPC program) Fig Ventilation network model/diagram of large metal mine (VnetPC program) Network simulation requires training and practice, as well as a thorough understanding of the inputs that are Size: KB. the ventilation course is held at a mine site and comprises classroom lectures together with field demonstrations. the course is of an applied nature and deals with such aspects as day to day measurements and more detailed ventilation planning and design. the training course is designed to cover specific topics prescribed by the participating. Dev£~lopment of coal mine fac(~ ventilation systems dUI"ing the 20th century D Uring the 20th century, the increased emphasis on worker health and safety and the advent of new mining equipment and methods led to many changes in mine face ventilation practices.

In some countries, coal mine legislation prohibits the use of booster fans. Air crossings Where intake and return airways are required to cross over each other then leakage between the two must be controlled by the use of an air crossing. The sturdiest form is a natural air crossing in Chapter 4. Subsurface Ventilation Systems. withdraw workmen from the face regions of the mine. In non-gassy mines if the ventilation is restored within a reasonable time the power may be turned on and work resumed without the necessity of re-examination. In gassy mines if the ventilation is restored within a reasonable time, the face regions and other places where methane is likely.
