Introduction To Industry Scenarios
The core of mine safety and monitoring is full scenario risk warning, 24-hour uninterrupted monitoring, explosion-proof/intrinsic safety, real-time data uploading, multi system linkage, unmanned operation, compliance with national mine safety supervision standards, zero accident goals, and extreme environment adaptation.
Typical measuring points:
Hydrological safety: underground/open-pit water level, water pressure, accumulated water pressure in the old goaf, inflow flow rate of tunnels, and pressure difference of waterproof gates
Roof safety: hydraulic support pressure, surrounding rock stress, anchor tension, tunnel convergence displacement, goaf pressure
Gas/ventilation safety: gas concentration, CO concentration, fan pressure, duct pressure difference, gas drainage pressure, air damper status
Equipment safety: vibration/temperature/pressure of coal mining machine/tunneling machine, tension/deviation of belt conveyor, hydraulic pressure of hoist, current/pressure of water pump
Emergency warning: pressure of fire protection pipeline network, pressure of dust prevention sprinkler, pressure of refuge chamber, and liquid level of emergency power supply

Addressing Industry Issues
Inaccurate safety monitoring leads to frequent false alarms/missed alarms
Ordinary instruments have low accuracy, large drift, and poor anti-interference, resulting in false alarms (shutdowns) or missed alarms (accidents), causing huge losses and high safety hazards.
Multiple system data islands, unable to link warning
Hydrological/roof/gas systems operate independently, data is not interconnected, unable to comprehensively assess risks, warning lags, and emergency response is slow.
Poor reliability and monitoring interruption in extreme environments
Underground humidity/dust/vibration, common instruments are prone to failure, monitoring interruption, safety blind spots, and uncontrollable risks.
High security and compliance requirements, data traceability
The national mine safety supervision requires data to be accurate, traceable, and tamper proof. Ordinary instruments have no storage/encryption and cannot pass acceptance.
Slow emergency response and expansion of accidents
Manual monitoring lags behind, response is slow, and equipment cannot be linked. Small hidden dangers evolve into major accidents, resulting in casualties and property losses
