Air Pollution in the Mining Sector Sources to Solution

The mining industry is essential to the manufacturing and infrastructure sectors but is also a significant source of environmental pollution. This paper discusses the critical environmental issue of air pollution in the mining industry, emphasizing the need for sustainable practices as global demand for minerals rises. It highlights how drilling, blasting, and crushing contribute significantly to air pollution in the form of dust and gases, which can impact the environment and human health.

The paper identifies dust (particulate matter) as the most significant air pollutant generated by mining activities. Dust is released from various stages like land clearing, drilling, blasting, crushing, and transportation of materials.

Additionally, gases like nitrogen oxides (NOx), sulfur oxides (SOx), methane, hydrogen sulfide, carbon monoxide, and excess carbon dioxide are emitted during mining processes, particularly from confined, underground mines where ventilation is limited. These gases can create a hazardous work environment for miners.

Health Impacts and Regulations:

• The paper emphasizes the severe health risks posed by exposure to dust and hazardous gases for mine workers and nearby communities. Pneumoconiosis, a lung condition caused by inhaling dust particles, is a significant concern.

• The paper mentions regulations like the Black Lung Benefits Act in the USA, which provides financial aid to miners suffering from coal worker’s pneumoconiosis (CWP).

The paper also has mentioned solutions to reduce air pollution from mining operations. These include:

• Modern mine planning techniques that minimize dust generation.

• Utilizing specialized equipment for dust suppression, such as water sprayers on roads and stockpiles.

• Deploying sensor-based air quality monitoring systems for real-time data collection on pollutants.

The paper showcases Oizom, a company offering sensor-based air quality monitoring systems specifically designed for the mining industry. Oizom’s devices, like Dustroid and AQBot, monitor various pollutants, including particulate matter (PM1, PM2.5, PM10), harmful gases (SO2, NO2, NH3, etc.), and meteorological parameters.

It also has case studies that demonstrate how Oizom’s air quality monitoring systems have aided different mining companies in India and Saudi Arabia in addressing their air quality challenges. These real-world examples highlight the practical application of sensor technology for improved environmental monitoring in the mining sector.
