  1. Reno, Nevada - June 11, 2008 12th US/North American Mine Ventilation Symposium • “Atmospheric monitoring systems for very large mines” by Albert E. Ketler, PE President

  2. Large mining operations demand -- • Long distance communications • Fast data and control response • Highest safety and reliability • Ease of installation and maintenance • Longest-life sensors • MSHA approvals, in depth • World-class computer software • Immaculate field telemetry hardware • Little or no • Lowest cost of ownership • Emergency stop (pull-key) monitoring • Full line of spares, sensors, alarms and accessories -- in stock! • Fast repairs; training and support

  3. Translation -- A high priority • Long-distance, high-speed, reliable, data communications

  4. Data Communications Rel-Tek’s first generation technology; ‘91 - ‘96

  5. Enter the “Link” Card • Rel-Tek’s second generation; ‘96 - ‘07

  6. Latest B-LINK Repeaters • Rel-Tek’s 2008 communication technology The “B-LINK” “DX-LINK”

  7. No need for costly optical fibers Handles 20-mile mines at 19.2KB with inexpensive twisted-pair cables The “BLINK”

  8. Fast response “Flash Telemetry TM” • Millennia-FT ~ Version 7.0, PC software and advanced field I/O hardware -- developed for very large coal mines ~ • Performance test: • A longwall coal mine running Millennia-FT with 340 sensors, 180 switches and 180 controls, communicating for 20-miles on low-cost twisted-pair cables ~ with multiple 3-mile branches The monitoring and control execution cycle time Previous 45 sec cycle time was cut to just 3.4 seconds. That’s 113 data registers per second.

  9. “FT” can avoid optical fibers Hey Purchasing, Cancel that fiber order! Millennia-FT™ (Flash-Telemetry) permits use of twisted-pair cables to 20-mile distances. Millennia is “hard coded” C++ programming that is very fast. Millennia-FT™ runs on Windows or Linux. Modbus interfacing is available. Twisted-pair cable enables low cost installation, easy troubleshooting and simplistic maintenance.

  10. Master Century Mine Beallesville, OH 7.6 miles

  11. Monterey Coal 7.6 miles

  12. Typical Millennia-DX Graphics

  13. Flash Telemetry -- fast and sure Results of a 13-hour test • Diagnostic screen for one of 68 addresses in this test Accuracy: • Even one error would be -- 99.99996% reliability • Such an error would be detected and corrected and repeated. • Zero data errors, 100% reliability Speed: • 18.4 addresses polled per second • Each DX4404 card address included 4-AI, 4-DI and 4-DO • Throughput of 220 data points per second
