Assistant General Manager

Underground Geological/Geotechnical mapping (face mapping & 3D logging) of Shaft, HRT, TRT, DC, GOC – DC, SFT, underground power house.  Geotechnical surface mapping & wall logging (Dam & Coffer Dam) Dam striping logging, geological logging of cut slopes for stability and foundation  Rock Mass Classification based on RMR, Q-system,  Recommendation for excavation method (Full Face, Heading & benching and Multiple drifting) in good & poor ground conditions  Probe holes ; advance prediction of rock mass condition / its treatment plan for weak zone in underground tunnels  Responsible for timely supports/treatment during excavation, support recommendation based on rock mass classification additional support as per site condition  Support system used (ISMB Ribs, Lattice Girder, Fore poles, wire mesh, Face bolt, Rock bolts, Self Drilling Anchor (SDA), SFRS, Plane Shotcrete, Pipe roof, Cement Grout ; Chemical grout) recommendation for treatment of cavity/collapse zone encountered during excavation  Prepared various kinds of Geological reports and document, interpreted with the research data recommended further analysis and study  Prepared of engineering drilling &; charging pattern as per rock mass class & specific charge obtained and reduced powder factor, also controlled over breaks during tunneling work in regular interval  Geotechnical instruments (MPBX, Load cell, Tape extensometer, Stress meter, Pizo Meter, Bi - Reflex Prism Target / Survey Reflector) installation, monitoring and analysis of data to know the behavior of rock mass in tunneling.  Core logging, analysis, report preparation and classification of rock mass based on RQD (Rock Quality Designation) value  SPT (Standard Penetration Test) in bore holes  Surface geological mapping, preparation of geological plan &; L-section along tunnel alignment and projection of rock mass at tunnel level  Collected several geological data and skillfully utilized for maximum over breaks approval  Prepared expected rock mass classification as per Trial Bore Holes and “Electro Resistivity Survey data before tunneling for safe work and analysis of project cost  Bore Hole Planning to prove the ore body continuity for underground mine/tunnel planning  Assisted the experts in handling the problems encountered during tunneling & mining that included, cavity formation treatments, weak zone treatments, water treatments  Prepared tendering geological reports as per geotechnical / geological surface investigation and Electro Resistivity Survey data.  Working in Co-ordination with shift in charge, Clients and excavation of work as per approved design /Tunnel scheme/drawings  Comparison between tender information and actual encountered ground conditions along tunnel based on site specific geological records for preparation of geological claims, delay analysis of underground excavation cycle time and time extension of the project (EOT) due to poor geological condition.
