ventilation at coal mines

Underground Mine Ventilation Technical Aspects of

Coal mines are particularly susceptible to the presence of natural gases. These include toxic gases such as hydrogen sulphide (H 2 S) but the most significant are flammable gases, of which the most common is methane (CH 4). However, other flammable gases may occur. Furthermore, flammable gases may occur not only in coal mines but also in metallic mines.

Basic Mine Ventilation

The quantity of air reaching each working face where coal is being cut, mined, drilled for blasting, or loaded shall be at least 3,000 cubic feet per minute unless a greater quantity is required in the approved ventilation plan. The quantity of air passing through the last open crosscut shall be at

Ventilation - underground COAL

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

Underground Mine Ventilation - 911 Metallurgist

25/10/2016  Mines with rock and water temperatures below 60° F. will have fair ventilation in the summer or the winter, but the air currents reverse their direction; in the spring and fall, the air currents will be sluggish and their direction will probably change daily.

Underground mine ventilation - Wikipedia

Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from surface via a shaft, ventilation raise or adit. The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans. An auxiliary ventilation system takes air from the flow-through system and distributes it to the mine workings via temporarily mounted ventilation fans, Venturi tubesand disposable fabric or steel ducting. Auxiliary fan a

Ventilation/Gas Control Introduction underground COAL

Ventilation/Gas Control. The ability to provide adequate ventilation to a longwall panel can be a major factor in the success of an installation, especially in gassy conditions. Most gassy mines now use some degree of gas pre-drainage of the seam being worked which greatly reduces the gas to be dealt with during longwall extraction.
