Ventilation is an essential measure in underground mining. We take a look at the different types of ventilation systems in mining below and why they are so vital.
From fires and dust explosions to gas emissions and windblasts, history tells us that the majority of mining accidents are ventilation-related.
Just seconds of breathing contaminated air such as carbon monoxide can have severe consequences.
While ventilation has no direct contribution to a mine’s production, failing to properly control airflow within an underground mining site can also lead to increased accidents and damage the health of workers, as well as decrease productivity and efficiency.
It’s no wonder then that ventilation is among the most important aspects of underground mining.
In order to ensure miners are safe in their workplace, effective equipment must be provided and correctly maintained.
The Different Types of Mining Ventilation Systems
To comply with this heavily regulated aspect of mine safety, suitable airways must be in place to allow clean air to come in and ensure contaminated air is filtered out.
There are several approaches mine operators can take to achieve a safe airflow and underground ventilation.
Ventilation on Demand (VOD)
Ventilation on demand for underground mines (VOD) has become an increasingly popular option.
This type of mining ventilation system uses sensors to detect where people and machinery are present and directs clean air to flow through these areas only, instead of the entire site.
Flow Through Ventilation
This variety is often the main and most natural option for underground mine ventilation.
The flow through ventilation methods sees air enter the mine from the surface via a shaft, which is then distributed by venturi tubes and controlled by ventilation fans and other types of regulators.
Ventilation Mining Curtains
Ventilation mining curtains can also be used to manage a site’s air requirements.
This approach works by channeling air to different areas and trapping any potential contaminants. Mining curtains are often the only practical option for underground use.
Carroll Technologies Group is a leading supplier of mining safety appliances throughout North America.
We supply a range of ventilation curtains from Bluefield Manufacturing and can customize them by size, grommet type, spacing and material as per customer request.
Bluefield’s catalog of mining ventilation curtains are designed to be tear-resistant, with the ability to withstand a wide range of temperatures.
They are lightweight, made from either a woven or double laminate polyethylene material, and customers can choose from varying degrees of transparency to allow for high visibility.
