Ventilation plans for underground mines. The manager of an underground mine must ensure that a plan of the ventilation system at the mine is kept at the mine that shows the direction, course and volume of air currents, and the position of all air doors, stoppings, fans, regulators and ventilating devices, in the mine.
1. METHODS OF AUXILIARY VENTILATION Presented by: Umair hassan Reg.# 0576 2. AUXILIAY VENTILATION Auxiliary ventilation is supplying air to the places in mine where main ventilation air stream is inadequate or unavailable. The practice of augmenting the main ventilation system is termed as auxiliary ventilation. 3.

two mines viz. The Moira and Kuardi collieries of Eastern Coalfields Ltd. (ECL). This paper also briefly deals with the methodology adopted by mine management for constructing cement concrete plugs from the surface. Experimental procedure, the results of the in situ investigation to determine the air leakage characteristics of the cement plug, and
Hence, mechanical ventilation becomes the only solution. Cost of Sufficient ventilation throughout mine can be as high as up to 50% of capital as well operating cost of whole mine (Brake, 2006).
Mine Ventilation Systems Ventilation is the control of air movement, its amount, and direction. Although it contributes nothing directly to the production phase of an operation, the lack of proper ventilation often will cause lower worker efficiency and decreased productivity, increased accident rates, and absenteeism.
Ventilation is among the most important functions in a mining operation. Since ventilation directly affects the health and safety of employees working underground, mine owners take the regulation

Air travels from the surface through the mine to this
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 source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.
Ventilation of underground mines Underground mines of all sizes require a formal, planned ventilation system to deliver fresh air to all working places. Mine ventilation is the process of supplying sufficient fresh air to the U/G workings to achieve these purposes, ensuring proper distribution amp; use of the air, and controlling the return to surface of contaminated air.
As mine operation is closely linked to market changes, you need to be able to scale up and down easily and efficiently. This isnt possible with a builtin cooling and underground mine ventilation plant, but with rentals, you can quickly modify your setup at a fraction of the cost of buying a new permanent plant.
Mining ventilation can account for up to 50% of an underground mines energy requirements, padding out the operational costs of a mine while also raising potential environmental concerns. Recent innovations in the mining ventilation space have sought to overcome some or all of these problems, with companies offering solutions that purport to be costeffective and environmentally sound.

A s mining activities advanced throughout the centuries, mines increased in depth and complexity, resulting in the development of new technologies and processes. 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
