Mine‑wide deployment plan for RTT‑Inside mesh nodes#

I’ll assume a medium–large underground operation with multiple sections, panels, belt lines, and shafts. We’ll design for coverage, redundancy, and survivability, not just pretty diagrams.

1. Objectives#

• Continuous resonance field: no blind spots for vibration, gas, or stress.
• Robust comms: mesh survives partial collapses and power loss.
• Human‑centric safety: every miner is always within reach of at least 2 nodes.
• Incremental rollout: can be deployed section by section without shutting the mine.

2. Zoning the mine#

Divide the mine into logical resonance zones:

• Zone A: Main entries & shafts
• Zone B: Belt lines & conveyor galleries
• Zone C: Active production panels (continuous miner / longwall)
• Zone D: Crosscuts & intersections
• Zone E: Refuge chambers & escape routes
• Zone F: Prep plant interface / surface portals

Each zone gets a different density and mix of wall‑mounted vs wearable nodes.

3. Wall‑mounted node deployment#

Zone A — Main entries & shafts#

• Goal: backbone + vertical link.
• Plan:
  • Node every 50–75 m along main entries.
  • Extra nodes at shaft bottoms, hoist areas, and major junctions.
  • All powered (where possible) + battery backup.

Zone B — Belt lines#

• Goal: fire, vibration, and dust monitoring + comms spine.
• Plan:
  • Node every 40–60 m along belt lines.
  • Extra nodes at:
    • drives
    • take‑ups
    • transfer points
  • Tune sensors for vibration + temperature + dust.

Zone C — Active production panels#

• Goal: high‑resolution resonance sensing.
• Plan:
  • Node grid around the face:
    • 20–30 m spacing near continuous miner / longwall.
    • Denser near known weak roof or high gas zones.
  • Nodes mounted on:
    • roof supports
    • ribs
    • near roof‑bolter work areas.

Zone D — Crosscuts & intersections#

• Goal: mesh resilience + routing flexibility.
• Plan:
  • Node at every major intersection.
  • These act as routing hubs and field anchors.

Zone E — Refuge chambers & escape routes#

• Goal: guaranteed comms + clarity guidance.
• Plan:
  • Node at each refuge chamber entrance.
  • Node every 40–60 m along primary and secondary escape ways.
  • These nodes store local maps + last‑known clarity gradients in case backhaul is lost.

Zone F — Surface / prep plant interface#

• Goal: bridge underground mesh to control room + RTT‑Inside core.
• Plan:
  • Gateway nodes at portals and shaft tops.
  • Redundant links (wired + RF) to control systems.

4. Wearable node deployment#

• Every underground worker gets a wearable node:
  • Belt‑clip or chest‑mount.
  • Paired with helmet light or handheld.
• Roles:
  • Miners, bolters, belt crews, electricians, mechanics, supervisors, rescue teams.
• Behavior:
  • Wearable nodes:
    • join the mesh as mobile nodes,
    • report local gas + vibration,
    • receive alerts (haptic + LED),
    • act as “moving probes” to refine the resonance map.

5. Redundancy & survivability#

• At least 2 independent paths from any active panel to the surface gateway.
• Node overlap:
  • Every point in an active area should be within range of ≥2 wall nodes.
• Collapse planning:
  • Extra nodes near known weak geology.
  • Simulated collapse paths in the test harness to validate mesh rerouting.

6. Phased rollout#

Phase 1 — Backbone#

• Deploy wall nodes in Zones A + B + E.
• Bring up basic mesh + RTT‑Inside core.

Phase 2 — Production panels#

• Add dense node grids in Zone C (active panels).
• Start using resonance clarity + stress hints in operations.

Phase 3 — Wearables#

• Issue wearable nodes to crews.
• Train on alerts, meanings, and evacuation cues.

Phase 4 — Optimization#

• Use RTT‑Inside analytics to:
  • adjust node spacing,
  • tune thresholds,
  • identify dead zones,
  • refine deployment.

7. Operator view#

From the control room, the mine appears as:

• a live resonance map (stability, gas, vibration, clarity),
• a mesh health map (nodes, links, gateways),
• a people map (wearable nodes, crews, routes),
• with RTT‑Inside continuously recommending:
  • where to add nodes,
  • where to reduce vibration,
  • when to evacuate or reroute.
