Nagpur :
The finding of 3000 million tonnes of good quality coal reserve in Andhra Pradesh a few months back by Omprakash Sarate, a scientist from the Birbal Sahni Institute of Palaeobotany in Lucknow, continues to bring appreciation and laurels for this botanist who originally hails from Nagpur.
Since Sarate did his doctoral research in the Institute of Science in palaeopalynology and coal petrology, the Institute felicitated him on Monday for his finding that has brought not just the Chintalapudi district in Godavari valley on the coal map of the entire country. He was honoured by the Institute director R G Atram on behalf of Alumni Association of the Institute and the Botany Society. He had been working in all the lower Gondwana formations of Wardha Valley and Godavari valley coalfields.
Sarate later told TOI that the AP government picked up the finding of coal reserve from his publication in the Journal of Palaeontological Society of India in December 2013. The government noticed the finding in September this year after which it got an independent survey done and was delighted to realize the size and quality of the reserve. “For AP, it is a jackpot as most of the coal reserves of undivided Andhra Pradesh were in Telangana region that is now a separate state,” he said.
Sarate’s study found good quality coal within 500m depth from Somavaram in Krishna District to Rajamundry in east Godavari district. The quality of Chintalapudi coal as compared to the Ramagundam and Talcher was better, especially its calorific value was much higher. Most of the coal is located between Aswaraopet, Chinthalapudi and Jangareddy Gudem fall in West Godavari district. The reserves are good for thermal generation as well as for steel plants.
Explaining palaeopalynology, Sarate said 10m of grass trough in a region generally got converted into 1m of coal got converted into carbon only due to bacterial and fungal activity. This initially must have resulted in brown coal and on compaction got converted into lignite that metamorphosed to coal. All this coal is about 260-270 million years old and was formed due to cold and humid conditions prevailing in the area.
Since these are deep seated deposits there could be even coal belt methane at the bottom. It will be possible to extract them only through underground mining.
Dr Surekha Kalkar, head of botany department, gave introductory remarks and introduced the guest. Atram explained how a particular kind of pollen grain can form the basis of presence of coal. Former Institute director M T Bharambe, M R Thosar, president of Alumni Association and Prof P S Jakhi, Incharge and secretary of the association also spoke . Roshani Singh, secretary of Botanical Society, conducted the programme.
