双高充填材料在充填采煤工作面中的应用

针对现有材料无法解决生产的问题,冀中能源股份有限公司自主研发双高充填材料,通过分析其反应机理以及结合在矿井下的应用实例,说明了双高充填材料作为矿井下充填材料具有强度发挥快、固水量大、方便操作等优点,为解放"三下"压煤问题的解决提供了有利的技术支撑,保证了矿山充填开采的良好效果。

Double High Filling Material Applied in Filling Mining Working Face

In order to solve the materials needed for backfill mining,Jizhong Energy Corporation independently developed double high filling material.By analyzing its reaction mechanism and the combined application examples in the mine,indicating that double high material as filling material had a strength of playing fast,solid water and convenient operation,etc.,which provided a favorable solution to"three down"pressure coal and ensured good results of coal mining with filling.
