Jiutong Changsheng brand vehicle-mounted automatic fire extinguishing device, underground mine car engine room water-based automatic fire extinguishing device, car-mounted automatic fire extinguisher, water-based engine room automatic fire extinguishing device, ultra-fine dry powder temperature sensing device developed and produced by Shandong Zhongdao Fire Equipment Co., Ltd. Automatic fire extinguishing devices, mechanical manual fire extinguishing equipment, and new energy perfluorohexanone battery compartment automatic fire extinguishing devices are widely used in the production and transportation of hydraulic oil field fracturing trucks and chisels in oil fields, coal mines, gold mines, iron ore and non-ferrous metal ore plants. Rock platform trucks, tunnel boring machines, loaders, excavators, mining trucks, wide-body dump trucks, trackless rubber-tyred trucks and other mining vehicles.
With the opening of intelligent coal mines, mining and transportation equipment are becoming more and more automated. At the same time, the installation of automatic fire extinguishing devices has also attracted more and more attention from mining companies. The following fire safety issues are common in coal mines:
1. Coal mines are poorly ventilated, which increases the corrosiveness of equipment: Generally, underground coal mines are located within a few hundred meters, and part of the groundwater will penetrate into the mine. Coupled with geothermal heat, heat dissipation of operating vehicles, and breathing of staff, etc., the temperature and humidity of the underground air will be significantly affected. Increases will cause adverse climate conditions. Therefore, mining vehicles will be 5-7 times more corrosive than surface vehicles, exacerbating fire safety hazards.
2. The concentration of gas and combustible gas in the mine exceeds the standard. In the process of mining coal, gas and mineral dust are produced. Gas and coal dust will explode when exposed to open flames or sparks, causing casualties and property losses. Fire safety issues are particularly prominent.
3. Frequent violations by staff. During the mining and transportation process, the maintenance of transportation vehicles is not in place, and even if the engine continues to work when there is a lack of coolant, the probability of vehicle spontaneous combustion increases.
