摘　　要：结合传统长壁垮落法和充填开采法的优点,根据邢东矿1221工作面具体开采条件,提出利用极不充分开采原理与冒落带注浆结合来控制地表下沉,为建筑物下开采提供了理论和技术支持。同时,对该方法的采充顺序和减沉效果做了进一步分析,结果表明:该方法减沉效果明显,下沉率会小于0.2。Combining with the advantages of the traditional long wall caving method and conventional filling technology method,according to the specific mining condition of 1221 mining face of Xingdong mine,super-subcritial extraction and cave backfill grouting combined is proposed to control the surface subsidence.It provides theory and technology support for mining under building.Meanwhile,the mining sequence and effect of reducing subsidence were analysis.Results show that effect of reducing subsidence is obvious by using this method,and the sink rate is smaller than 0.2.
