Coal demand in the country is yet to peak as the Economic Survey 2021-22 projects coal demand in the range of 1.3-1.5 billion tonnes by 2030, an increase of 63 percent from the current demand. Thus, as of now, there is no scenario of energy transition away from coal affecting any stakeholders involved in coal mining.

Coal dust is both a health and safety issue. The high concentration of coal dust produced in either open-pit or underground coal mines can lead not only to the death of miners suffering from pneumoconiosis but also to coal dust explosions and even gas explosions, which can result in major personal injury and economic loss.

Coal dust is an essential component of iron casting. To put it simply, iron casting involves melting the iron into a liquid state and pouring it into a mould. The mould is removed when the metal solidifies in the desired shape. Other metals employ coal dust in their manufacturing processes, but this page will focus on the iron casting application.

Coal mining presents a number of specific hazards, ranging from collapse and flooding to dangerous explosions. Dust created by mining activities presents a hazard because its pervasive nature creates a number of breathing-related issues for people, as well as maintenance issues for machinery. Dust also creates a potentially explosive environment.

During the process of mining, methane is released from the coal seam and surrounding rock strata. This can present a high risk of explosion at concentrations in air of 5 to 15 percent. In recent years, scientists have developed techniques to eliminate or dilute methane emissions before and during the mining process.
