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-
underground This energy supply consists of static head & velocity head, but only static head is available for moving the airflow H gain = H s + H v Overall or Mine Heads In a mine ventilation system with a single fan and a single discharge, the cumulative energy consumption is called the total mine head. Engineers will often, in planning, want to sum all of the expected flow-energy losses to ...

Basic ventilation system underground where D is a ventilation door or airlock, R is a mine regulator and 1, 2, 3 are working places with a surface exhaust fan. To maintain adequate ventilation through the life of a mine, careful advance planning is
Online courses, short courses and live webcasts about Mine Ventilation for mining and geoscience from Edumine.
Industrial electric mine ventilation fans are used primarily for underground mining operations. Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove noxious gases. Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from surface via a
A review of ventilation and gas management in underground mines By B Robertson FAusIMM(CP), Consulting Mining Engineer and A Self MAusIMM, Principal, ACMC Pty Ltd This is an excerpt from a paper to be presented at The Australian Mine Ventilation Conference 2017, which will be held in Brisbane from 28-30 August.
Correctly Estimating Primary Airflow Requirements for Underground Metalliferous Mines D J Brake1 and T Nixon2 ABSTRACT A common problem for many mines is insufficient ...
Ventilating underground mines takes a lot of power. In northern countries, the cold air from outside must be heated before being sent underground, which takes even more power. Integrating a range of technologies allows these power costs to be substantially reduced.
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.

COST SAVING STRATEGIES IN MINE VENTILATION. Euler De Souza . The Robert M. Buchan Department of Mining, Queen's University . Kingston, Ontario, Canada. ABSTRACT. Energy associated with ventilating an underground operation comprises a significant portion of a mine operation's base energy demand and is consequently responsible for a large percentage of the total operating costs. Ventilation ...

Guidance about underground air quality and ventilation. Highlights importance of ventilation in underground mines - primary and secondary ventilation and risk-based hygiene management plans.
underground mining methods. In early 2010, Diavik began mining and processing initial ore from its new underground mine; underground mining operations are expected to continue beyond 2020. The initial mine ventilation system was an exhausting (pull) system with fresh air supplied by a fresh air raise and a main ramp. Return air was exhausted via two raises and a secondary ramp. The system …
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.
Background. The main objective of an underground mine ventilation system is clear: to provide air flows in sufficient quantity and quality to dilute contaminants to safe amounts/concentrations where personnel are required to travel and work.
Adequate ventilation is a prerequisite for any underground mining operation. It is necessary to reduce the losses of fresh air, cross contamination with return air, to prevent gas build up(e.g. Methane) by filling non ventilated cavities and to seal off old works to prevent underground fires.
Without ventilation, the air in a mine is filled with dangerous contaminants. Miners may work at depths of a mile or more underground where contaminants such as carbon monoxide, as well as the dust created from the mining cycle exist. Worker safety is essential to any mine's operation and success, but also presents challenges.
