三相泡沫防灭火技术在陈家山煤矿的应用

三相泡沫防灭火技术是将气、固、液三相介质经发泡后形成的大量泡沫注入采空区或火区,覆盖在浮煤上,有效地抑制煤的氧化。三相泡沫在铜川矿务局陈家山煤矿的成功使用,有效地预防了综放工作面采空区遗煤的自燃发火,实现了安全生产,进一步证实了三相泡沫具有降温、阻化、惰化、抑爆等综合防灭火性能。

Application of Three - phase Foam Technology for Fire Prevention and Extinguishing in Chenjiashan Coal Mine

The technology using three-phase foam for fire prevention and extinguishing is to inject great deal foam formed by foaming of three-phase medium consisting of gas,liquid and solid into goaf and cover float coal with the foam so as to inhibit coal oxidation effectively.The successful use of three-phase foam in Chenjiashan Coal Mine prevents residual coal spontaneous combustion in goaf,thus safety production is achieved.Results show that three-phase foam is provided with comprehensive performance of fire prevention and extinguishing such as cooling,inhibition,inerting,explosion suppression and so on.
