Underground Mine Ventilation Technical Aspects of

3. 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 use of the air, and controlling the return to surface of contaminated air.

Underground Mine Ventilation A Case Study

In the view of mine ventilation, it is an important aspect of underground mining in which it is required to clear all harmful gases, as in coal mines removes fumes from blasting and occasional exhaust from diesel equipment and also at the same time it provides fresh air to the miner ïs which improves their efficiency.

Mining - Mining - Ventilation and lighting: Ventilation is an important consideration in underground mining. In addition to the obvious requirement of providing fresh air for those working underground, there are other demands. For example, diesel-powered equipment is important in many mining systems, and fresh air is required both for combustion and to dilute exhaust contaminants. In addition, when explosives are used to break hard rock, ventilation

MINE VENTILATION SYSTEMS

To maintain adequate ventilation through the life of a mine, careful advance ventilation planning is essential. Advance ventilation involves the consideration of two principal factors: (1) the total volume flow rate of air required by the mine, and its satisfactory and economic distribution, and (2) the pressure required by the mine fan(s). A well designed ventilation system should be 167

Ventilation and Cooling in Underground Mines

The main objective of mine ventilation is the provision of sufficient quantities of air to all the working places and travel ways in an underground mine to dilute to an acceptable level those contaminants which cannot be controlled by any other means. Where depth and rock temperatures are such that air temperatures are excessive, mechanical refrigeration systems may be used to supplement the

5 key innovations in mining ventilation

Powering ventilation systems consumes 25-50% of the total energy requirements of an underground coal mine. If the NHEET project can successfully replicate the natural ventilation properties of the Creighton mine, it could not only displace the capital and operational costs of a refrigeration and heating system, it could reduce the overall energy consumption of mines – reducing costs while also improving the environmental impact of underground mining.

Guidance about underground air quality and ventilation

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.

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 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 mine ventilation is electricity to power the ventilation fans,

Guidance about underground air quality and ventilation

Ventilation in an underground mine is of critical importance to the occupational health and safety of underground employees. The atmosphere underground is limited and confined, and is thus readily reduced to a sub-standard (or even dangerous) condition if contaminants (e.g. gases, dusts, fumes) produced in the course of operations are not controlled, safely extracted or diluted to acceptable levels.
