Dewatering wells in open cast mining

Level
Dewatering wells in open cast mining

Overview

In open cast mining, the groundwater levels must be continuously reduced to protect the mining area from flooding and the excavation walls from instability due to water pressure. A large number of dewatering wells with submersible pumps are kept in operation for this purpose. A continuous water flow prevents the pump shaft from blocking due to the effects of hardening clay/iron oxide deposits. To regulate the pump output, precise level measurement is required in each of the up to 750 m deep wells.

Inventory System

VEGA Inventory System (VIS) is a web-based software for real-time data acquisition, visualization, and logistics management of inventory levels in storage tanks and silos. Companies can manage their inventories proactively, ensuring greater flexibility in delivery schedules, expanding optimization options, and reducing stock discrepancies. Precise, real-time visualization of stocks allows deviations to be quickly identified, minimizing financial impact. The system combines reliable VEGA measurement technology for liquids and bulk solids with secure cloud-based or on-premises software, providing the basis for intelligent and strategic decisions for optimal inventory management. VIS supports both internal inventory monitoring and Vendor Managed Inventory (VMI) applications, where suppliers manage customer stock replenishment using real-time level data.

  • Real-time inventory monitoring across all connected storage locations via web browser or mobile app
  • Four visualization modes — Chart, Graphic, Map, and Trend — for comprehensive stock visibility
  • Color-coded traffic light status system (green/yellow/red) for instant stock level assessment
