The design and implementation of effective mine dewatering and slope depressurization systems is an important component of many surface and underground mining operations. WMC has designed, implemented and operated large-scale dewatering systems for mines throughout the world. We have experience in high flow, deep well dewatering systems for mines that produce many thousand gallons per minute. We also have extensive experience in low-permeability hydrogeologic systems where pit slope depressurization is essential to maintain stable slopes. In addition to dewatering/depressurization design, we develop systems such as rapid infiltration basins to dispose of excess water in an environmentally sound manner. Services that we offer on dewatering and depressurization projects include:
- Hydrogeological investigations and testing
- Modeling of dewatering/depressurization systems
- Detailed design of wells, drains, sumps and other dewatering measures
- Selection of pumps, controls, pipes and other dewatering infrastructure
- Dewatering system management and optimization
- Design of systems to manage or dispose of excess water
- Assistance to mining personnel during dewatering operations
- Turnkey dewatering systems
Project Examples:
| Title: |
Las Cristinas dewatering system design
|
| Location: |
Venezuela
|
|
|
| Client: |
Placer Dome
|
| Description: |
WMC conducted extensive hydrogeological field investigations at this proposed mine site in the jungle. The site receives over 3 metres per year of rainfall and is adjacent to major rivers. The work included pre-feasibility and feasibility level design and costing. It also included the production of detailed dewatering system design drawings for construction.
