The United States has witnessed a concerning surge in the incidence of diseases like Coal Workers’ Pneumoconiosis (CWP), despite numerous efforts aimed at prevention. This study delves into the realm of respiratory health by investigating the deposition of dust particles within the respiratory tract and lungs. By analyzing particles of varying sizes, shapes, velocities, and aerodynamic diameters, we aim to gain a comprehensive understanding of their impact on deposition patterns. This insight could potentially drive changes in dust exposure protocols within mining environments and improve monitoring practices. The interplay of several critical factors, including particle characteristics and an individual’s breathing patterns, plays a pivotal role in determining whether particles settle in the lungs or are exhaled. This paper provides a comprehensive literature review on Respirable Coal Mine Dust (RCMD), with a specific focus on examining particle deposition across different regions of the airway system and lungs. Additionally, we explore the utility of Computational Fluid Dynamics (CFD) in simulating particle behavior within the respiratory system. Predicting the precise behavior of dust particles within the respiratory airway poses a significant challenge. However, through numerical simulations, we aspire to enhance our understanding of strategies to mitigate total lung deposition by comprehensively modeling particle interactions within the respiratory system.

“…Logical investigations have demonstrated that exposure to particle in the dusty environment condition causes development of chronic bronchitis, increased respiratory manifestations, and so forth. Coarse particles PM10 and fine particles PM2.5 can cause the greatest issue since they can get profound into the lungs [3,10]. One of the perspectives with respect to airborne dust is the spreading of combustible coal dust and its deposition in the working which may cause explosion [13].…”

“…Exposure to dust particles can prompt to genuine medical issues. Logical examinations have connected particle exposure to development of diseases like bronchitis, increased respiratory symptoms, and so on [3,10]. Specifically, dust particles under 10 μm in size 2 of 11 (respirable) are a wellspring of annoyance and these easily enters the lower zone of the respiratory organ [3,7].…”

“…Inhaling respirable coal dust causes some of the most hazardous illness such as Coal Workers Pneumoconiosis (CWP) also called as deadly black lung disease, progressive massive fibrosis (PMF) and chronic obstructive pulmonary (COP). Coal dust explosions is another hazard to coal mining activities [3,7]. Hence, the environment dust density has to be continuously monitored [4].…”

The dust density within the environment must be continuously monitored in open cast mines. Water sprinklers are used to suppress the dust in mining field. Water sprinklers capacity used are of 28,000 and 70,000 L. These conventional water sprinklers comprise of 4 kinds of sprinkling thus the operator must choose and actuate any 1 type of sprinkling which is appropriate to suppress the dust. The traditional water sprinkler is worked physically by the operator that is operator turns on the type of sprinkling dependent on the dust seen by him. This technique does not completely suppress the dust and it’s not accurate. Furthermore, water is squandered if the dust density is according to the directions given by central pollution control board. Supportive to the above background, it is necessarily essential to actualize the water sprinkling system automatically which measures the dust density contained in mine atmosphere and likewise module will consequently actuate the sprinkling so as to suppress the dust in the environment. This technology is compatible to inbuild display for continuous monitoring of dust concentration also the system has both auto/manual operation. At the point when the dust concentration crosses the admissible value automatically system will activate solenoid driver to start out the sprinkling activity. Therefore, the designed dust monitor module is employed to implement an automatic system, utilizing advanced technology to monitor the density of fine dust particles in the mining environment & accordingly the sprinkling operation is actuated with minimal human intervention.
