Jharia coalfield is one of the most important coalfields in India. The extraction of this specific coalfield is to obtain prime cocking coal which is the great source of energy. Opencast mining is one of the essential and vital mining method which involves various activities due to which the ecological changes and environmental degradation occur. When opencast mining is done, the soils found on upper most layer get severely damaged due to blasting and drilling etc. The opencast mining causes harmful effects on the insects living in the soils. As the nutrient quality and microbial activities of the soil system get disturbed hence the bio-diversity of soil insects of concerning mining areas gets disturbed badly. The living conditions of many insects get changed. This paper presents the result of the study carried out in mining areas i.e. Lodna and Bastacola of Jharia coalfield. The selected soil insects were collected from five different sites of Lodna and Bastacola for study in mining areas and from Baliapur and Sindri for the study of non-mining areas. The obtained results are very useful to understand the mining impact on selected soil insects.
