Abstract – The Singrauli region of India, located in Madhya Pradesh is widely known as the energy capital of India due to the presence of numerous coal mines and coal-based thermal power plants. These industries play an important role in electricity generation and economic development, but they also contribute significantly to environmental pollution, especially air pollution. Large amounts of coal dust are released during open-cast coal mining, blasting, and transportation activities, while thermal power plants generate fly ash during the burning of coal. These fine particles, including PM2.5 and PM10, spread in the atmosphere and make the surrounding environment dusty and polluted. Continuous exposure to coal dust and fly ash has serious impacts on the health of the local population, causing respiratory problems such as asthma, bronchitis, and breathing difficulties. In addition, dust deposition affects vegetation and disturbs the ecological balance of the region. Therefore, effective pollution control measures such as dust suppression techniques, proper fly ash management, installation of electrostatic precipitators, and development of green belts are necessary to reduce air pollution and

.protect both the environment and public health in the Singrauli region

Introduction

The Singrauli region, located in the states of Madhya Pradesh, is an important industrial area known for its large coal reserves, extensive coal mining activities, and several coal-based thermal power plants. These industries play a significant role in electricity generation and industrial development in India, but the continuous expansion of coal mining and power plant operations has created serious environmental challenges, especially the deterioration of air quality in the surrounding region. Coal mining operations such as drilling, blasting, excavation, crushing, and transportation release large amounts of coal dust and suspended particulate matter into the atmosphere. These particles mainly include fine particulate matter such as PM10 and PM2.5, which can remain suspended in the air for a long period and spread over nearby residential areas. In addition to mining activities, thermal power plants burn coal to generate electricity and produce large quantities of fly ash and bottom ash as by-products. Fly ash contains very fine particles along with mineral components such as silica, alumina, iron oxides, and trace heavy metals that easily disperse in the air and significantly contribute to air pollution. The continuous release of coal dust and fly ash has several environmental impacts, as dust particles settle on plant leaves and reduce the process of photosynthesis, affecting vegetation growth and agricultural productivity, while the deposition of ash particles may also alter soil properties and water quality, disturbing the ecological balance of the region. Air pollution caused by coal mining and thermal power plants also affects human health because fine particulate matter can enter deep into the respiratory system and lungs, leading to breathing difficulties, asthma, bronchitis, coughing, and other respiratory diseases among the local population. To minimize these environmental and health impacts, effective pollution control and management measures are required, including regular water spraying on mining roads and working areas, the use of dust suppression systems, controlled blasting techniques, and proper covering of coal during transportation to reduce coal dust emissions. Similarly, thermal power plants can control fly ash emissions through the installation of electrostatic precipitators, bag filters, and efficient ash handling systems, while the proper utilization of fly ash in cement manufacturing, brick production, and construction materials can help reduce ash disposal problems. In addition, the development of green belts and plantation around mining areas and power plants can help capture airborne dust particles and improve the overall air quality of the surrounding environment, making these measures important for protecting both the ecosystem and the

Objectives of the Study

He main objective of this study is to examine the impact of coal mining activities on air quality in the Singrauli region and to understand how coal dust generated during mining operations contributes to environmental pollution. The study also focuses on analyzing the role of fly ash emissions from coal-based thermal power plants in increasing the concentration of particulate matter such as PM10 and PM2.5 in the atmosphere. Another important objective is to evaluate the environmental effects of these pollutants on vegetation, soil quality, and the surrounding ecosystem. In addition, the study aims to understand the health problems faced by people living near coal mines and thermal power plants due to continuous exposure to polluted air. Finally, the

study seeks to identify and suggest effective pollution control measures and management practices that can help minimize air

.pollution and reduce the environmental impact of coal mining and thermal power plant emissions in the Singrauli region

Methodology

:Dust Sampling and Air Quality Assessment

The study of coal mining dust and fly ash pollution in the Singrauli region can be carried out by collecting air and environmental samples from different locations such as areas near coal mines, coal transportation routes, residential villages, and thermal power plants. Air samples can be collected using air quality monitoring instruments such as High-Volume Samplers (HVS) and PM10 and PM2.5 samplers to measure the concentration of suspended particulate matter present in the atmosphere. Dust deposition can also be studied by placing dust collection plates or filter papers at selected sampling sites for a fixed period so that airborne dust particles settle on the surface and can later be weighed and analyzed in the laboratory. In addition, fly ash samples can be collected from ash ponds or surrounding areas of thermal power plants to study the physical characteristics and composition of ash particles. During the sampling process, environmental parameters such as wind direction, temperature, and humidity are also recorded because these factors influence the dispersion and concentration of dust and fly ash in the air. The collected samples and monitoring data are then analyzed to determine the level of particulate pollution and to evaluate the environmental impact of coal

:Data Analysis of Air Sample Collection and Observation

.Table 1. Data Analysis of Air Sample Collection and Observation

Result

The results based on the observed air sample data show that the concentration of particulate matter at all sampling locations is higher than the Indian National Ambient Air Quality Standards (CPCB NAAQS). At the coal mine area, the recorded PM10 concentration is 168 µg/m³ and PM2.5 is 92 µg/m³, which are higher than the standard limits of PM10 (100 µg/m³) and PM2.5 indicating that mining activities generate significant coal dust in the surrounding environment. The coal transportation ,(µg/m³ 60) road shows the highest pollution level with PM10 182 µg/m³ and PM2.5 105 µg/m³, mainly due to heavy movement of coal trucks and uncovered coal transport that increases airborne dust. Near the thermal power plant, the observed PM10 concentration is 156 µg/m³ and PM2.5 is 88 µg/m³, suggesting that fly ash emissions and ash handling operations contribute to particulate pollution in the air. In the nearby residential area, PM10 (132 µg/m³) and PM2.5 (74 µg/m³) are also above the permissible limits, which indicates that coal dust and fly ash particles spread to surrounding villages and affect the local environment and public health. Overall, the observed data clearly indicate that particulate matter levels in the Singrauli region exceed the national air quality

.standards, highlighting the significant impact of coal mining dust and thermal power plant fly ash on air quality

Conclusion

The presents study indicates that air pollution in the Singrauli region is significantly influenced by coal mining dust and fly ash emissions from thermal power plants. The observed concentrations of PM10 and PM2.5 at different sampling locations are higher than the limits prescribed by the Indian National Ambient Air Quality Standards (CPCB). Mining operations such as drilling, blasting, excavation, and coal transportation generate large amounts of dust, while thermal power plants release fine fly ash particles during coal combustion. These pollutants spread in the surrounding environment and affect ecological conditions as well as the health of the local population, causing respiratory problems and breathing difficulties. To reduce these impacts, several local-level measures can be implemented that directly benefit nearby communities, such as regular water spraying on mining roads and transportation routes to control dust generation, proper covering of coal during transportation, and maintenance of roads used by heavy coal trucks to reduce airborne dust. Thermal power plants should ensure the effective functioning of electrostatic

precipitators and proper fly ash management, including the utilization of fly ash in brick manufacturing and construction materials. In addition, plantation and development of green belts around mining areas, power plants, and nearby villages can help trap dust particles and improve local air quality. Community awareness programs and continuous air quality monitoring at the local level are also important so that people remain informed about environmental conditions and preventive measures. Through these pollution control strategies and the involvement of local communities, it is possible to reduce air pollution, protect the

.surrounding environment, and improve the health and living conditions of people in the Singrauli region

Discussion

The analysis of the collected air samples from different locations in the Singrauli region indicates that the concentration of particulate matter such as PM10 and PM2.5 is higher than the limits prescribed by the Indian National Ambient Air Quality Standards (CPCB). The observed data show that the highest level of particulate pollution is found near coal transportation roads, followed by coal mining areas and locations near thermal power plants, while nearby residential areas are also affected due to the dispersion of coal dust and fly ash in the atmosphere. These results clearly indicate that mining activities, coal transportation, and fly ash emissions from power plants are major contributors to air pollution in the study area. Continuous exposure to such polluted air can create environmental problems and increase health risks for the local population, particularly respiratory diseases and breathing difficulties. However, the study also suggests that air pollution in the region can be reduced through proper environmental management and the implementation of effective dust control techniques at the local level. One of the most practical and immediate solutions is the regular water spraying on coal transportation roads, mining sites, and coal handling areas, which helps in controlling airborne dust and prevents the spread of fine particles into the surrounding environment. The use of covered trucks or tarpaulin sheets during coal transportation can also reduce the release of coal dust into the air. In mining areas, the adoption of controlled blasting techniques, dust suppression systems, and proper maintenance of haul roads can significantly minimize dust generation. Thermal power plants can further reduce air pollution by ensuring the efficient operation of electrostatic precipitators (ESPs), bag filters, and proper fly ash handling systems, which capture fine ash particles before they are released into the atmosphere. In addition, the development of green belts and plantation around mining sites, power plants, and nearby villages can act as natural barriers that trap dust particles and improve air quality. These measures not only help in reducing air pollution but also provide direct benefits to the local communities by improving environmental conditions, protecting vegetation, and reducing health risks associated with air pollution. Therefore, the combined application of these technical and management strategies can play an important role in controlling coal dust and fly ash pollution and improving the overall environmental quality
