India ranks third in coal production. However, the country has to import coal in order to meet the rising demand for coal. In India, coal mining is conducted using two methods: underground and opencast methods. The underground method is suitable for extraction of deeper coal seams, whereas opencast method is suitable for shallow coal seams.
