CMPDIL Invents New Dust Control Technology
In order to minimize and control the fugitive dust in mining areas, Central Mine Planning and Design Institute Limited (CMPDIL), Ranchi has invented a “System and Method for Controlling Generation and Movement of Fugitive Dust ''.
An overview of the news
CMPDIL, Ranchi is a consultancy subsidiary of Coal India Limited.
It has obtained a patent for the invention in December, 2022 (Patent No. 416055).
This system can be used in mines, thermal power plants, railway sidings, ports, construction sites where coal or other mineral/fugitive material is stored under open sky.
The invention relates to the synchronized application of windbreak (WB) and vertical greenery system (VGS) for reducing generation and dispersion of fugitive dust.
WB and VGS are positioned in the upwind and downwind directions with respect to the blown dust source, respectively.
WB reduces the speed of the oncoming wind towards the source and hence, reduces the intensity of the ambient air to pick up dust while it blows over the source.
The VGS acts as a filter and reduces the amount of residual dust moving towards the receptors in the downward direction along with the air.
Therefore, there is a significant reduction in the dust concentration in the ambient air at various receptors located in the down-wind direction.
What is Fugitive Dust?
Fugitive dust is a form of particulate matter that contributes to air pollution.
It refers to the dust particles which like to run in the air without a directed place.
It is produced from various sources that come in contact with the air.
