Efforts to rescue the 41 workers trapped inside the collapsed SilkyaraBarkot tunnel in Uttarkashi gained steam on Tuesday as a team of rathole miners set to work. Interestingly, the practice of rathole mining is banned by the National Green Tribunal. The team is doing manual drilling through the debris after the final segment of the damaged ...
Abstract Soil pollution due to coal mining and its associative activities has become a serious environmental concern in India. The byproducts of coal mining are often disposed directly to the bare lands, significantly altering the characteristics of soil up to a considerable extent. These stacks of discarded rock wastes under the influence of various geological agents, viz., wind, running ...
During the coal mining process, a significant amount of coal wastes is produced, including (1) mining wastes, (2) washery wastes, and (3) secondary processing wastes. Since 2017, the annual global CMWs are estimated to be 315 million tons for underground coal mining. This results in the disposal of a considerable volume of wastes at waste dumps.

The mining industry in India is a major economic activity which contributes significantly to the economy of gross domestic product (GDP) contribution of the mining industry varies from % to % only but going by the GDP of the total industrial sector, it contributes around 10% to 11%. Even mining done on small scale contributes 6% to the entire cost of mineral production.
Despite government's repeated assertions for the sustainable mining extraction and development of rural and tribal communities living near the vicinity of mining areas, these have not been converted into implementable solutions. The natural resources from rural and tribal areas are being exploited to meet the everincreasing requirements and aspirations of the affluent groups. With the above ...
Strip Mining. In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock,, the 'overburden' is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out ...
Uses of Coal. It is mainly used to generate heat and electricity. It is used in households and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.
The overall process of coal exploration and mining involves six separate but interdependent and overlapping components: • Exploration: the identification and geological assessment of a new coalbearing area; • Mine Design: the design and economic evaluation of the most appropriate mining operation to make use of the coal in that area;
