Post ESA funding opportunities
• OMSHR continues to be interested in innovative technology ideas to improve MINER safety and health– ESA fund was a one-time appropriation and future
contract awards will come from OMSHR base budget– Broad Agency Announcement is the contract solicitation
mechanism– Mine Test Bed tentatively planned as a competitive
solicitation– Other funding opportunities are available through the
CDC/NIOSH grants program• Relatively few contract awarded post ESA
![Page 18: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/18.jpg)
Current contracts
• Our continued focus is the post disaster functioning of systems• Primary Systems and Secondary Systems• Current focus is on Secondary Communications Systems and
techniques to improving survivability of systems– Fewer number of active components is generally better for
both survivability and reliability
![Page 19: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/19.jpg)
Primary Communications
• Primary communications systems are those that:– Operate in the conventional radio bands– Use small antennas that allow the miner to have
wearable devices with long battery life– Have sufficient throughput for general operations
• Leaky feeder and node based systems are examples of primary systems
![Page 20: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/20.jpg)
Secondary Systems
• Medium Frequency Systems and TTE Systems are viable secondary systems that can provide alternate communications paths out of the mine
• A secondary system is one which:– Operates in non-conventional frequency bands– Uses a large antenna that is best suited for fixed locations
or portable applications– Does not have sufficient throughput for general operations
![Page 21: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/21.jpg)
Coverage of Critical Areas with Wireless Systems
Wireless Coverage has tremendous safety advantage for the miners
![Page 22: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/22.jpg)
Survivability …….. The Challenge
What happens if 2000 feet of all entries are lost?
![Page 23: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/23.jpg)
Survivability……..The Goal Alternate Communication Paths
![Page 24: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/24.jpg)
Survivability the Approach
• The principal challenge for post accident operation is survivability
• Lesson learned: Survivability is most practically achieved through alternate communications paths.– No practical way to harden primary communications
infrastructure to survive any conceivable event
• Survivability has as much to do with the design and installation as it does the technology– Mine specific design approach
![Page 25: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/25.jpg)
Alternate Communications Paths for Leaky Feeder
![Page 26: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/26.jpg)
Alternate Communications Paths for Node based systems
![Page 27: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/27.jpg)
Alternate Communications Paths for Node based systems (Mesh)
![Page 28: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/28.jpg)
Alternate Communications Paths• Ideally the alternate communications path is “truly diverse”
and highly reliable• Independent failure mechanisms
– No shared components between the primary and alternate path that would fail from a common event
• Minimum number of active components (those that require electricity) yields the highest reliability
• Secondary Systems offer the best potential for an alternate communications path– A borehole directly to the miner would be the “ideal”
alternate communications path

Interoperability Challenge
• Interoperability with digital and multi-channel communications is more complicated
• How do we ensure that only emergency traffic is directed to this secondary system?
Hybrid Systems will need to be developed to address the “bandwidth mediation” challenge.

Applications Research
The introduction of wireless communications and tracking systems in the mines introduces endless possibilities of new applications for health, safety, and productivity improvements.– Similar to the introduction of the Internet in to homes– Need to avoid the dot com boom – bust pitfall– Future applications should be driven by clearly
defined requirements and solid needs analysis
![Page 39: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/39.jpg)
Applications Research (cont.)
OMSHR will be considering additional research relative to the application and use of C/T systems. Areas of potential interest include:– Mine wide sensor systems using C/T backbones to improve safety– Roof control– Atmospheric Monitoring– Mine rescue applications– Biological monitoring of miners or rescue team members– Proximity Detection– Others
![Page 40: NIOSH Communications and Tracking](https://reader036.vdocuments.us/reader036/viewer/2022062323/56815b74550346895dc96e7c/html5/thumbnails/40.jpg)
Systems Quality AssuranceThe introduction of wireless communications and tracking systems also introduces the need to ensure the quality and compliance of these systems. – Measurement tools and techniques need to be developed– Predictive tools and analysis techniques are needed.– Design of Systems– Calculating Survivability of systems – Performance Goals need to be established in a manner that
enables compliance determination. • Examples, tracking “accuracy”, system survivability, etc.
