Capture Of Respirable Dust Using Maintenance Free Impingement Screen, Neeraj Kumar Gupta
Capture Of Respirable Dust Using Maintenance Free Impingement Screen, Neeraj Kumar Gupta
Theses and Dissertations--Mining Engineering
Dust produced during mining activities has a detrimental effect on both miners’ health and operations’ safety. There is no definitive treatment for coal miners’ pneumoconiosis (CWP), which is caused by prolonged inhalation of respirable dust. Elevated coal dust concentrations have also been shown to cause several disastrous explosions in the United States and worldwide, resulting in the death of miners and loss of operations. Flooded-bed dust scrubbers are used on all modern-day continuous miners. These devices cleanse the dust-laden air and assist in bringing fresh air towards the mining face. Scrubbers use a multi-layered fibrous screen to capture airborne particles. …

Theses and Dissertations--Mining Engineering
Heavy industries, such as mining, generate dust in quantities that present an occupational health hazard. Prolonged exposure to the respirable dust has been found to result in many irreversible occupational ailments in thousands of miners. In underground mining applications, a variety of scrubbing systems are used to remove dust near the zones of generation. However, the wire-mesh type fibrous screens in the flooded-bed dust scrubbers used on continuous miners, are prone to clogging due to the accumulation of dust particles. This clogging results in a reduced capture efficiency and a higher exposure to the personnel. This research establishes the Vortecone, …
