TW is defined as the number of all types of workers in the total population per sq km. Farming is the largest private-sector enterprise in India, where nearly 58.9% of the workers depend upon agriculture for their income and livelihood [33]. In the coal mining region, along with agriculture, various workers are also involved in mining or industrial activity (quarrying, transportation, blasting, etc.) for daily wages. These workers have direct interaction with the coal product (coal blocks, coal powder, coke, etc.) or wastes (mine spoils, coal ash, dust particles, etc.) causing serious impacts on their health. In the study area, Saunda, Patratu, Lapanga, Jainagar, Sirka, Dari, Labga, Koto, Terpa, etc., are the villages having a higher worker population (>252 workers/km²) (Figure 2.5b).
