AI Technical Summary
Existing coal mine belt conveyor systems pose risks of frictional fires and fatigue damage in soft rock coal roadways. The lack of a systematic source prevention solution makes it difficult to achieve precise spraying and rapid extinguishing of ignition points, leading to safety hazards of gas combustion or explosion in high-gas mine environments.
A flame-retardant transportation system was designed to prevent external fires caused by soft rock deformation and belt friction. The system employs a five-layer composite flame-retardant belt, a hot-cast flame-retardant roller, a mobile spray-type fire extinguishing structure, and intelligent monitoring components to form a complete external fire prevention and control system. The system includes a flame-retardant belt, a hot-cast flame-retardant roller, idler rollers, monitoring components, and fire extinguishing components, which can adapt to belt misalignment and scraping, and accurately locate and extinguish fires with spray.
It effectively resists the problems of belt scraping, frictional heat generation and static electricity accumulation caused by deformation of soft rock roadways, realizes all-dimensional monitoring and dual early warning, accurately locates the fire point and extinguishes fires without dust or secondary hazards, improves fire handling capabilities and ensures the safe and stable operation of underground transportation systems in coal mines.
