摘要
探讨了膏体充填采煤用外加剂中的流化组分、引气组分、保坍组分、早强组分的作用和作用机理,指出充填膏体中加入上述4种组分可以保证充填膏体具有优异的保水性能,保持良好的泵送性能,并能降低堵管风险。
To study the effect and mechanism of the fluidizing component, the air-entraining agent, the slump retaining component,the acclerating component in the paste backfilling admixture for coal mining.To point out that through the above four components to the fill paste,the fill paste has excellent water retention capacity and pumpability, and the pipe blockage risk canbe decreased.
