Mining Operations Optimize Dewatering Processes

Dewatering ProcessesEffective water management is critical to both open-pit and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively managed dewatering processes typically employ continuous water level monitoring. Mine dewatering is usually undertaken for several reasons:
  • To ensure stability of mine walls during and after excavation—In open-pit mines, a water table that is too high can destabilize mine walls, haulage roads, and slopes. Water pressure reduces the stability of mine walls and can lead to sliding and collapse of materials in the slope. In underground mines, the inflow of water must be controlled to prevent flooding; however, a balance must be maintained so that groundwater levels are not needlessly depleted.
  • To optimize mine production and reduce operational costs—Effective dewatering operations create dry conditions so that low strength aquifer sequence materials (sands, gravel, and clays) can be safely excavated, reducing drilling and blasting costs. Additionally, wear and corrosion on equipment is minimized, and the possibility of pump burn out is reduced by accurately monitoring drawdown. Haulage costs for unsaturated excavated material is significantly less than for saturated materials, further reducing operational cost.

Active Stormwater Runoff Monitoring

Active Stormwater Runoff Monitoring
Stormwater runoff is a major contributor to surface water pollution, perpetuating ever-increasing state and federal demands for stormwater runoff control and reporting. A wide range of flexible instrumentation enables Teledyne Isco to meet non-point source discharge monitoring requirements.

Regulating Stormwater Discharge

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from potential sources that include both point and non-point sources. Operators and managers of storm sewer systems, construction sites, croplands, industrial sectors, and urban areas may be required to obtain authorization to discharge stormwater, in accordance with both federal law, and often more stringent state and local regulations.

To meet these requirements, businesses, municipalities, and other organizations must develop comprehensive stormwater monitoring programs. These programs typically consist of several parts, including the collection and storage of storm event data on rainfall, flow, and measured pollutant levels, as well as taking water samples during the storm event for laboratory analysis. Representative sample collection is dependent upon crucial factors such as timing, flow volume, and water quality.

Rapidly changing storm conditions can present several challenges to accurate sample collection, monitoring of system status, program adjustment needs, and data retrieval. With instrumentation from Teledyne Isco, a site-specific system can provide precise automatic sampling with real-time data collection and flexible programming. All of this and more can be achieved from remote locations.

Remote Monitoring + Sampler Commands

The 2105C (CDMA) and 2105G (GSM) Cellular Interface Modules allow the user to remotely enable an Isco Model 6712 portable or Avalanche portable refrigerated wastewater sampler while simultaneously monitoring current site conditions, with flow and water quality data logged and transferred to a secure server database. Immediate access to data and the ability to send commands to a sampler from off-site can reduce labor and fuel costs. Additionally, the user can wait until a storm has passed to retrieve the samples, meaning safer working conditions.

Basic Operation

The primary functions of the system are:

  • Log real-time water quality and flow data
  • Automatic sampler enabling by predetermined conditions
  • Push data to secure server 
  • Remotely enable/pace sampler
  • Retrieve sampling reports
