Mining vehicles in both open-pit and underground operations are subjected to long-term high-load working conditions. Areas such as engine compartments, onboard power distribution boxes, and hydraulic oil lines tend to accumulate oil and dust, which, under high temperatures, frequently trigger oil-related fires. Traditional dry powder extinguishing methods offer poor cooling capacity, cause severe equipment corrosion, and are prone to re-ignition, making them inadequate for on-site protection needs. GMfire has launched an automatic fire suppression system for mining vehicles equipped with a specialized water-based extinguishing agent. Leveraging advantages such as ultra-fast cooling, flame retardation and suppression, and clean environmental friendliness, this system specifically addresses fire hazards in the core areas of mining vehicles, building a solid safety defense line for mine haulage fleets.

This system focuses on precise protection for two high-frequency fire-prone zones: the engine compartment and the onboard power distribution box. The water-based extinguishing agent features outstanding penetration capability, enabling it to permeate through oil scale and carbon deposits to directly reach the fire source, rapidly reduce ambient temperature, interrupt the combustion reaction, and fundamentally prevent re-ignition. At the same time, the agent is mild in nature and non-corrosive; after extinguishment, it does not damage engine wiring, electronic control components, or precision mechanical structures, significantly reducing equipment maintenance costs and downtime—perfectly suited for the continuous production demands of mining operations.

The mining site environment is complex, with high dust levels, strong vibrations, large temperature fluctuations, and high humidity, all of which impose stringent requirements on the stability of fire protection equipment. The entire system adopts a fully sealed structural design, and both piping and detection units are reinforced against vibration. It operates reliably under long-term bumpy conditions and dust accumulation, effectively eliminating false alarms, missed detections, and equipment failures. The system is equipped with an all-encompassing, dead-zone-free detection matrix, with multiple point‑based real‑time fire source detectors covering blind spots such as compartment corners, wiring gaps, and the interiors of distribution boxes, enabling early fire identification and early response, thereby seizing the critical golden time for fire suppression.

Backed by mature product performance, the system has been deployed in major coal mines across Indonesia, Pakistan, Mongolia, and other countries. In one particular coal mine, multiple explosion‑proof trackless rubber‑tyred vehicles were custom‑fitted with the water‑based fire extinguishing system. The installation optimized the spray nozzle positions and piping layout in the engine compartment, effectively resolving early‑stage oil fires and localized smoldering fire risks, while perfectly adapting to the humid, confined underground conditions—earning approval from the mine’s safety department upon acceptance.

In summary, the water‑based fire extinguishing solution of the mining vehicle automatic fire suppression system perfectly aligns with the oil‑fire prevention needs of mining vehicles. Combined with full‑area detection and ruggedized design for harsh working conditions, it balances fire suppression efficiency, equipment protection, and long‑term stability. Based on actual mining working conditions, GMfire provides practical and specialized fire protection products, continuously ensuring safety for various vehicles in coal and non‑coal mines, and supporting the safe and stable operation of mining production.
