The equipments for Liquid Carbon Dioxide (CO₂(l)) storage and transportation, the ground vaporous CO₂(l) fire extinguishing system, and the underground CO₂(l) direct fire extinguishing system are independently researched and developed. The self—pressurization system of the storage tank is able to make the CO₂ keep a liquid state without icing. For the ground vaporous CO₂(l) fire extinguishing system, the CO₂(l) is changed into gaseous CO₂ through the electrothermal vaporization and air temperature vaporization. And then the vaporous gaseous CO₂ is piped into a pressure stabilizing tank at a stable value of 1.5MPa. The gaseous CO₂ from the pressure stabilizing tank is transported at a pressure of 0.5MPa down to the coal mine in order to prevent or to extinguish the coal mine fire. The CO₂(l) could be directly transported by the fire extinguishing train consisting of a number of single storage tanks near to the underground high temperature zone or the fire zone, which is able to rapidly cool the high temperature zone or extinguish the fire. The CO₂(l) fire xtinguishing equipments are used to extinguish fire in the 122 fully mechanized workface of Zhaojin Coal Mine. The application results show that the scientific equipments are able to rapidly and effectively reduce the temperature, the concentration of oxygen and coal spontaneous combustion index gas in the fire zone, eliminate the hazards of target fire., authors=ZHANG Chunhua^1,2, WANG Jiren³, ZHANG Ziming⁴, ZHANG Yadong⁴, authorsList=ZHANG Chunhua;WANG Jiren;ZHANG Ziming;ZHANG Yadong, authorCompany=1.

研制了液态二氧化碳CO₂(l)的储罐、地面汽化防灭火系统和井下直接防灭火系统.储罐的自增压系统可使CO₂在其内保持液态状态而不结冰;CO₂(l)的地面汽化灭火系统可以将CO₂(l)在地面运用电热汽化器和空温汽化器汽化, 气态的CO₂在稳压罐内稳压达到1.5MPa后, 以0.5MPa的压力通过管道输送至火区进行防灭火;CO₂(l)防灭火列车可以直接将其运到煤矿井下的高温地点或火区附近, 快速降温、灭火.照金煤矿122综采工作面防火工程实践表明, CO₂(l)可以快速有效降低火区环境的温度、氧气和煤自燃指标气体浓度, 消除火灾隐患., authors=张春华^1,2, 王继仁³, 张子明⁴, 张亚东⁴, authorsList=张春华;王继仁;张子明;张亚东, authorCompany=1. 辽宁工程技术大学矿业技术学院, 辽宁葫芦岛 125105;2.
