· Productivity measures of Indian coal mining activity in underground and opencast mining have shown a steady increase (especially from the 1980s onwards), when measured in output per manshift (OMS). However, this cannot be fully attributed to improvement in actual productivity of any of the inputs of production.
The opencast mining is now the most mainstream technique for the significant bit of the world''s coal creation. In India, the demand of coal in the year 2016-17 was estimated 884.87 MT whereas the domestic availability of coal was estimated
