  2. PLANNING: DPSIR framework for mining impacts DRIVING FORCES impact/risks reduction regulations good management practice remediation demand for mineral resources IMPACTS RESPONSE mineral resource exploitation waste production emissions STATE PRESSURES source pollution natural resource degradation life quality degradation landuse conflicts pathway natural background historical pollution baseline other landuses receptor Conceptual framework developed by EEA for environmental assessment and reporting Introduction: impact assessment and spatial planning problems specific to mining

  3. Life cycle of mineral commodity (on-site) prospecting treatment extraction storage Life cycle of mine project exploration production remediation development closing PLANNING: Life Cycle Analysis

  4. FOREGS Underground: high information uncertainity Natural background PROBLEMS SPECIFIC TO MINING 1. Exploration: the geological environment Spatial problem: 3D Non-renewable natural resources

  5. environmental impacts collected data useful for environmental protection 2. Exploration:preparing for mining Long-term exploration Investigations during mine exploration project

  6. other industries: use infrastructure Mining: brings infrastructure and industry secondary / indirect impacts CLOSING !! 3. Development and environmental planning Mineral deposit  no alternatives for location Concession right  actual mining: long-term delay

  7. pollution • Natural background • Baseline HISTORIC MINING change of technology • Market change of mineral mined • Market by-products • Long-term suspension 4. Operation All mining projects are unique (deposit type:confined vs. disperse, etc; open vs. underground; etc) • Operation for several decades • Processing in place • Collected data useful for environmental protection

  8. Long-term monitoring 5. Closing and Remediation Reopening as market prices change Huge amount of waste Underground can never be fully restored • Perfect remediation impossible: • Huge amount of waste • Underground • Natural background

  9. Spatial aspects for regional planning RESPONSESociety • Regional planning: SEIA • Regional/EU legislation PRESSURE Emissions Hazard: local/point source IMPACTS • smelters (air) • historic mine regions (soil, water, society) REGIONAL ASPECTS • STATEEnvironment • Geology of mineral deposit (natural background) • Groundwater system • 3D problem • geology, hydrogeology, mineral chemistry • spatial uncertainty
