Mines need a Comprehensive Hydrogeological Report for CGWA NOC and environmental clearance. We build it from field data: well inventory, pumping tests, ERT profiles and a calibrated groundwater flow model that runs the mine plan pit stage by pit stage. The output is a defensible estimate of inflow, the drawdown cone and its radius of influence, and a mitigation and monitoring plan the Expert Appraisal Committee can accept.
What you get
- Comprehensive Hydrogeological Report (CHR) for CGWA NOC and EC
- Mine seepage and dewatering estimates by empirical methods and numerical models
- Groundwater flow model with drain boundaries for each mine stage
- Water management plan and mine water reuse
- Replies to EAC and CGWA queries on the model
- Piezometer networks and water quality monitoring
Who it is for
Coal, limestone, iron ore, zinc-lead and silica sand mines, and the mine-planning consultants who work for them.
Common questions
Can you answer EAC comments on an existing model?
Yes. We review the conceptual model, boundaries and calibration, and revise the model or the narrative so each comment is answered on the record.
Do you work outside India?
Yes. We have carried out a hydrogeology study for a greenfield iron ore project in Nasarawa State, Nigeria.
