MSHA-Approved Mine Rescue Team Communication System: Key Features & Innovations

DESCRIPTION

This document outlines the characteristics of an MSHA-approved communication system tailored for mine rescue teams in coal mines. It highlights the use of medium-frequency inductive radio components, easy deployment methods, and battery-powered units for effective communication in challenging environments. With 75% of New South Wales mines utilizing similar systems, the document addresses the deployment methods, including handheld radios and section radios at fresh air bases. It also discusses the importance of realistic training and the continuous improvement of tracking systems to enhance safety.

  1. Mine Rescue Team Communication System

  2. Characteristics • Medium Frequency • Inductive Radio Components • MSHA Approved • Easy to Deploy • Battery Powered

  3. Users • 75% of New South Wales, Australia Mines Rescue Centers – at present • MSHA - purchased set for Beckley, WV in mid-1990’s • Several (2?) Mines in U.S.

  4. Typical Deployment • 3 Handheld Radios on Rescue Team • 1 Section Radio at Fresh Air Base

  5. Present Status • 1993 Design Presently Deployed • 2005 Design in Prototype Testing • May 2006 Expected Completion for A&CC Intrinsic Safety Submission

  6. Where MSHA Can Help • Prioritize (Fast-Track) Approval Process • Minimize Approval Costs at A&CC Small Market, Small Companies • Place Less Emphasis on Trophy Competition. Place More Emphasis on Realistic, Site-Oriented Training

  7. Vehicle and Personnel Tracking System

  8. Characteristics • Low-Power, Short-Range, Burst Transmitters (Tags) • Operate at UHF • Stationary Tracking Receivers • Part of Atmospheric Monitoring System

  9. Deployment Methods Transmitter • Magnetic Mount to Machines • Can be Modified and Submitted to MSHA as a Smaller Unit. (Stand-Alone or Cap Lamp)

  10. Receiver • Attached to 4-Conductor, Copper AMS Cable. Power and Data. • Strategically Placed in Mine • Typical Range ~ 100 feet • Logs of Station Activity Available on Surface Computer

  11. Planned Improvements • Portable Receiver for Use With Search and Rescue Operations.

  12. Important Design Criteria • System Must be: Intrinsically Safe Reliable Economical Rugged Accurate Within Reason Functionally Simple
