Thisresearch group works mainly in the area of paste backfilling for both underground coal and metalliferous mines, hydraulic stowing for coal mine and coal ash utilisation in opencast backfilling. The group has its strong presence since the inception of the Institute (1956) more than 74 years ago. It has to its credit 10 numbers of research projects funded by various Ministries of Government of India and more than 600 industry sponsored projects of challenging in nature. This research group has received National Award for fly ash utilisation for backfilling in underground coal mines awarded jointly by Ministry of Science and Technology, Ministry of Environment and Forest and Ministry of Power.
