Communications and Tracking for Underground Mines

Since the Sago, Aracoma and Darby accidents and subsequent enactment of the Mine Improvement and New Emergency Response Act of 2006 (MINER Act), MSHA has investigated new communications and tracking technologies. Initially, MSHA conducted a search of available technologies, published a request for information and hosted a public meeting in Washington DC in March 2006. Based upon the findings from this investigation, MSHA selected a cross-section of new technologies and conducted tests at the CONSOL Energy McElroy Mine to evaluate potential application of such technologies in underground coal mines. The findings were published in a report that is available at the link provided below.

In response to the identified industry need, MSHA received a significant number of approval requests for a new generation of communications and tracking technology. MSHA devoted significant resources to the investigation of these new technologies and has issued many new approvals which are listed at the link below. Additional requests continue to be received. Our Technical Support Directorate is reviewing these products and proposals and assisting interested manufacturers in obtaining MSHA approval. We have also been working with the National Institute of Occupational Safety and Health (NIOSH) as well as the NMA/BCOA Communication and Tracking Partnership to assist interested parties in arranging field tests of their systems to facilitate development. MSHA wishes to thank NIOSH, the NMA and the BCOA for their efforts in furthering the development of these important technologies.

Manufacturers must obtain the appropriate MSHA approvals for the systems to be used in gassy underground mines. We encourage all interested manufacturers of communication and tracking technologies to contact us.

Interested parties should contact David Chirdon at chirdon.david@dol.gov


Current Status
    As of April 29, 2009, MSHA is processing 38 approval applications for communications and tracking technology. Since the beginning of 2006, we have issued 83 new or revised approvals for communications and tracking products. Significant approvals issued in April include the Active Control Technology’s Wi-Fi Telephone.

    We have observed 61 tests or demonstrations of 31 different communications and/or tracking systems at various mine sites. We have met with representatives from 68 communications and tracking system companies. To date, we have had discussions with various vendors regarding 182 different proposals for development of mine communications and tracking systems.

    We are providing presentations on the communications and tracking program policy letter (http://www.msha.gov/regs/complian/ppls/2009/PPL09-V-01.asp) at a variety of venues including the NIOSH Communication and Tracking Workshops in Denver, CO on May 13 and 14 and in Charleston, WV on May 19 and 20. Details on these workshops can be found at: http://www.msha.gov/events/upcomingevents.asp.
