mine and auxiliary fans to overcome the resistance of ducts in blind headings. Fans may also be classified into two major types with reference to their mechanical design. A centrifugal fan resembles a paddle wheel. Air enters near the centre of the wheel, turns through a right angle and moves radially outward by centrifugal action between the blades of the rotating impeller. Those blades may

Hurricane Mine Auxiliary Fans | AirEng

Our ‘Hurricane’ Fans are Auxiliary Mining Fans used in underground coal mines to supplement primary fan ventilation. They boost the air flow if the existing air flow is not sufficient. ‘Hurricane’ Mine Auxiliary Fans can be used as either forcing systems where fresh air is pushed into mine headings or exhausting systems that draw out contaminated air.

Development Face Ventilation | Introduction | underground

The adoption of longer pillar centres (>100m) in longwall mines coupled with higher in situ gas regimes experienced in deeper mines has necessitated that mines utilize a more effective ventilation system comprising electrically powered auxiliary fans attached to ventilation ducting to course air through the working areas. Auxiliary fans add another complication and another piece of machinery

Ventilation Basic Mining Process underground COAL

A few mines do use intake or "forcing" fans, particularly in the US where exhaust adits are mined to outcrops. The roadways underground are divided into 2 groups, those carrying fresh air into the workings ( "intake airways" ) and those carrying used air back out ( "return airways" ).

Underground mine ventilation Wikipedia

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. The largest component of the operating cost for

point through the mine to the surface. * Exhausting fans create a low pressure point immediately inby the fan. Air travels from the surface through the mine to this low pressure point. Airflow in a mine is induced by pressure differences between intake and exhaust openings. The pressure difference is caused by imposing some form of pressure at one point or a series of points in the ventilating

Utilization of booster fans in underground mines

operating practices developed by the mining industry, and recommendations provided by fan manufacturers. The principles involved in the design and installation of booster fans are illustrated by a sample problem which is solved using a ventilation simulator in two configurations: a single-fan system and a two-fan system. The latter is used to highlight the benefits of using a booster fan

01.01.2019· In coal mines, methane gas and spontaneous combustion of coal are the most common causes for fires and explosions, with other ignition sources, including open flames, faulty electrical equipment, and hot metal smears caused by worn cutter bits. Blasting used to be a frequent cause of coal mine explosions, but the use of permissible explosives along with the mechanization of the

Impact of using auxiliary fans on coal mine ventilation

Substituting auxiliary fans for brattice eliminates this source of resistance, with improvements in system efficiency and cost. Also, in some mines, the leakage that leads to spontaneous combustion can be reduced. The benefits obtained by several different brattice and fan substitutions have been studied by Mine Ventilation Services, Inc., Lafayette, California, under contract to the U.S
