SPAR Engineering’s innovative mine-wide energy management system provides control strategies for underground ventilation that will dramatically reduces a mine’s energy consumption while maximizing productivity, profitability and worker safety. Typically a mine’s ventilation system operates at peak capacity when it may not be required. SPAR’s OUVS (Optimized Underground ventilation System) is a highly advanced solution that controls the ventilation system air flows in order to meet the mine’s production activities. It analyzes and responds to air quality data, the location of mining personnel and vehicles and optimizes the ventilation requirements and adjusts it accordingly. SPAR’s OUVS is configured to each mine’s unique requirements using open architecture with built in interface to allow system integration with existing or new process controls.

Benefits:

Following are some of the achievable benefits from OUVS.

  • From 30% to 50% reduction in a mine’s energy consumption with respect to ventilation
  • Reduce strain on power distribution system related to fixed speed starters
  • Measureable reduction in Carbon emissions
  • Optimized Ventilation-On-Demand - Efficient use of ventilation air
  • Enhanced air quality, health & safety
  • Maximize production through optimum air distribution

Control Features:

The Optimized Underground Ventilation System (OUVS) system can be interfaced with the mine’s existing infrastructure or run as a standalone system with following minimum control and monitor functions:

 Manual for surface fans, auxiliary fans, bulkhead air flow regulators, dampers and other ventilation related components are controlled manually from the central control room for starting, stopping, speed and/or CFM speed adjustments and/or to disable them for any reason from automatic functions.

 Scheduled Control starts/stops of the surface fans, auxiliary fans, bulkhead air flow regulators, dampers and other ventilation related components are controlled at specific times of the day as per production schedule.

 • Ventilation On Demand Based on the underground environmental conditions due to the presence of the vehicles, presence of Co2 after blasting, will automatically direct the air to the area where is it required and reducing into the areas where it is not likely to be required, by opening and closing of the dampers and starting/stopping of the air directing fans etc.

 Environmental Monitoring Typical environmental monitoring sensors such as SO2, CO, NOx and temperature are integrated into OUVS system to monitor, control and report the underground environmental conditions.

 System Features:

 • Open platform/architecture with an open-architecture design, that easily integrates and transfers device intelligence to most of the industry standard DCSs and PLCs.

 • High Reliability With redundant system and dual communication network make the system reliable and safe.
