Matrix Design Group, LLC (“Matrix”) and Alpha Natural Resources (“Alpha”) were recently presented with the Mine Safety and Health Technology Innovations Award at the Sentinels of Safety Awards Presentation in Washington, DC. This National Institute for Occupational Safety and Health (“NIOSH”) award recognizes mines and companies that have made extraordinary efforts to apply technology in ways that will improve mine worker safety and health. Matrix and Alpha received the 2013 Coal Award for “Next-Generation Sensors for Atmospheric Monitoring Systems (“AMS”).” The improved air velocity, low-power methane, and flexible-use carbon monoxide (“CO”) sensors are designed for daily use in coal mines and improve mine safety by detecting potentially harmful developments in a mine’s ventilation network. The sensors were developed by Matrix for its new MX3 permissible voice and data communications system package. The sensor bundle was designed to work with a variety of existing AMS and CO monitoring systems and has the necessary features to allow post-accident functionality. “Matrix is excited to be recognized for the development of next-generation equipment as part of this important project with Alpha,” said Matrix President, Aric Pryor. “Our development team, working in partnership with Alpha engineers and mine personnel, has created an innovative set of advanced sensors that are accurate, easy to use, and work with variety of existing AMS and CO monitoring systems. We believe these sensors will offer immediate benefits for both mine ventilation management and miner safety at underground mining operations.” For more information about these advanced-technology sensors, or other Matrix safety systems, please visit www.matrixteam.com.
