🧪 RTT‑Inside Virtual Mine Test Harness

Simulates vibration, gas drift, stress propagation, and mesh‑node behavior#

This harness is designed to:

• generate realistic underground resonance events
• test node firmware logic
• test mesh routing under stress
• validate S‑N‑R and clarity scoring
• simulate collapses, methane pockets, and equipment vibration
• run deterministically or stochastically

It’s written in pseudo‑code so we can port it to Python, Rust, C++, or your preferred environment.

1. Virtual Mine Model#

class VirtualMine:
    layers          // roof, seam, floor
    tunnels         // graph of nodes/edges
    equipment       // miners, belts, crushers
    gas_fields      // methane/dust pockets
    stress_fields   // roof load, floor heave
    vibration_srcs  // equipment vibration emitters
    mesh_nodes      // simulated RTT-Inside nodes

2. Initialization#

mine = VirtualMine()

mine.load_layout("section_c_layout.json")
mine.spawn_nodes(count=120, spacing="adaptive")
mine.seed_gas_pockets(random=True)
mine.seed_stress_fields(baseline="normal")
mine.place_equipment(["CM-04", "RB-11", "Belt3"])

3. Event Generators#

A. Vibration Events#

function generate_vibration_event(source, magnitude, freq):
    for node in mine.mesh_nodes:
        distance = node.distance_to(source)
        attenuation = exp(-distance / VIBRATION_DECAY)
        node.vibration += magnitude * attenuation * sin(freq * t)

B. Gas Drift Events#

function generate_gas_event(origin, concentration):
    for cell in mine.gas_fields:
        drift = compute_drift_vector(cell, ventilation_flow)
        cell.level += concentration * drift_factor(drift)

C. Stress Propagation#

function propagate_stress():
    for layer in mine.layers:
        for cell in layer.cells:
            cell.stress = weighted_avg(
                neighbors(cell).stress,
                cell.local_load,
                vibration_coupling(cell)
            )

D. Collapse Simulation#

function simulate_collapse(region):
    for cell in region.cells:
        cell.stress = 1.0
        cell.vibration = 1.0
        cell.gas_level += random_spike()
        disable_mesh_nodes(cell)

4. Node Behavior Simulation#

Each node runs the same firmware loop we defined earlier.

for node in mine.mesh_nodes:
    node.read_virtual_sensors()
    node.compute_resonance()
    node.detect_alerts()
    node.route_messages()

5. Test Scenarios#

Scenario 1 — High Vibration + Roof Stress#

generate_vibration_event(CM-04, magnitude=0.9, freq=60Hz)
propagate_stress()

Expected:

• clarity ↓
• stress_hint ↑
• alerts from nodes near CM‑04

Scenario 2 — Methane Pocket Drift#

generate_gas_event(origin=Panel3, concentration=1.3)

Expected:

• gas_level ↑
• drift_vector →
• nodes warn before threshold

Scenario 3 — Belt Fire Risk#

generate_vibration_event(Belt3, magnitude=0.8)
mine.equipment["Belt3"].temperature += 20°C

Expected:

• vibration hotspot
• heat signature
• critical alert

Scenario 4 — Partial Collapse#

simulate_collapse(region=SectionC)

Expected:

• nodes die
• mesh reroutes
• clarity crater
• control room sees collapse vector
