山東中道消防研製的煤礦車輛發動機艙自動滅火裝置，有水基型自動滅火裝置，超細乾粉自動滅火裝置，機械式手動滅火系統，感溫式自啟動滅火等被廣泛應用於煤礦車輛發動機自動滅火領域，可根據車輛作業環境和結構的不同選擇機械式和電動式啟動方式，其主要採用探測技術、報警技術、滅火技術整合於一體，具有可操控性強、滅火速度快、滅火無汙染、避免二次復燃。
用煤量的不斷增多，煤礦壓力會越來越大，在瘋狂開採的同時，煤礦生產、運輸車輛的負荷也是與日俱增，而且，井下煤礦車輛一般存在火情難發現，滅火難、火情易擴散甚至爆炸等情況，後果非常嚴重，中道消防研發生產的煤礦車輛自動滅火裝置可將滅火阻燃劑通過藥劑管路直達火源燃燒點，實現快速滅火，減少煤礦車輛消防安全事故的發生。下面簡單介紹下該裝置的應用設計。
The increasing of coal, coal mine pressure will be more and more big, the crazy mining at the same time, the coal mine production, the transportation vehicle load is also growing, and the underground coal mine vehicles generally exist fire is difficult to find, the fire, the fire spreading even explosion, etc., consequence is very serious, the tathagata fire research and development production of coal mine vehicle automatic fire extinguishing device can fire flame retardant chemicals through line direct fire burning point, achieve rapid fire, reduce coal mine vehicles on fire control safety accidents. The following is a brief introduction to the application design of the device.
礦車專用新型水基自動滅火系統屬於全淹沒滅火系統，其滅火機理為化學作用和物理作用，具有清潔、無毒、對設備無汙染、電絕緣性好、滅火效能高、滅火速度快、無復燃等特點，該系統功能完善，動作可靠，長期貯存不易洩漏，可有效撲滅車輛發動機艙、油路及輪胎處火災。
The new type of water-based automatic fire-extinguishing system for mine car belongs to total submergence fire-extinguishing system. Its fire-extinguishing mechanism is chemical action and physical action. It has the characteristics of clean, non-toxic, no pollution to equipment, good electrical insulation, high fire-fighting efficiency, fast fire-extinguishing speed and no re ignition; The system has perfect function, reliable action, long-term storage is not easy to leak, and can effectively extinguish the fire in engine compartment, oil way and tir.
該自動滅火系統中的啟動管路上安裝有定製的低洩高密閥， 能有效防止由於啟動裝置慢性洩漏引起的系統誤噴，提高了裝置的安全性能。
The automatic fire extinguishing system is equipped with a customized low-discharge high-density valve in the starting pipe line, which can effectively prevent the system from misspraying due to the chronic leakage of the starting device and improve the safety performance of the device.
