介绍了我国煤矿充填开采现状。分析了充填开采上覆岩层运移规律和连续曲形梁形成的基本条件，得出了连续曲形梁和充填密实度与关键层的量化关系；描述了充填材料的制备及运输、固体充填装备、巷道固体充填及工作面固体充填技术的特点及其工艺。分析了固体充填开采采充平行作业、充填自动控制和煤矿井下“采选充留”一体化的技术装备体系。提出为保证充填的长期效果的散装固体改性充填技术方法。认为充填开采要向精准充填开采，建设全过程生态矿山努力。

The current status of coal mining in China was introduced.The migration law of overlying strata and the basic conditions for the formation of continuous curved beams in backfilling mining were analyzed,and the quantitative relationship between continuous curved beam,filling density and key layers was obtained.The characteristics and technology of preparation and transportation of filling materials,solid filling equipment,roadway solid filling and working face solid filling technology were described.The integrated technical equipment system of solid filling mining and filling parallel operation,automatic control of filling and the integration of "mining,processing and filling" in underground coal mine were analyzed.In order to ensure the long-term effect of filling,a modified bulk solid filling technique was proposed.It is believed that filling mining should make efforts to build ecological mines in the whole process with precise filling.
