Partha Das Sharma (P.D.Sharma) is Graduate (B.Tech – Hons.) in Mining Engineering from IIT, Kharagpur, India (1979)
He has very rich experience both in Mining operation and Marketing / Export / offering of Technical Services of Explosives & blasting, ANFO, Bulk explosives, Blast designing, Controlled Blasting etc. Visited number of countries in Africa, South East Asia etc.
He was associated with number of mining PSUs and explosives organizations, namely MOIL, BALCO, Century Cement, Anil Chemicals, VBC Industries, Mah. Explosives, Solar Explosives etc. Later, he gained very good experience in Infrastructure Industry for planning, execution and implementation of Aggregate quarry operation including crushing. He was Vice President (Marketing and technical Services) in one of the Infrastructure Company located at Pune (India) working for large Infrastructural companies such as IVRCL, L&T infra, B.G.Shirke Construction Technologies, J.M.Mhatre Infrastructure, IJM Infra etc., for Road projects and EPC activities. Later he became Mining Head in one of the biggest construction & infrastructure group in Pune (India) having annual turnover about $ 100 million. Now he joined an Infrastructure company based in Nagpur India) as Adviser Blasting Tech, working for a Highly Mechanized Underground Metal Mines project of PSUs with equipment such as Sanvik Drilling Jumbos, LHDs, LPDTs etc.
He has also studied extensively Environmental Engineering.
He is also a Consultant.
He has presented number of technical papers in many of the seminars and journals on varied topics like Overburden side casting by blasting, Blast induced Ground Vibration and its control, Tunnel blasting, Drilling & blasting in metalliferous underground mines, Controlled blasting techniques, Development of Non-primary explosive detonators (NPED), Hot hole blasting, Signature hole blast analysis with Electronic detonator, Acid Mine Drainage, etc.
