摘　　要：为了对由采动、构造、水弱化等因素耦合导致的斜井冒顶灾害进行治理,采用复合式化学充填加固材料固结形成人工假顶,使固结材料与冒落岩块粘结成有自身承载能力并有一定强度的完整围岩,并用FLAC3D对充填加固方案进行数值模拟。模拟结果表明:采用复合式化学充填加固方式后,垂直位移降低了85%,充填体强度达到了2 MPa,高于周围泥岩体的强度,治理效果明显。In order to control the roof falling disaster in mine inclined shaft oecurred jointly by mining activities, structure, water softening and other factors, the complex chemical filling and reinforcement material was applied to form the artificial roof of the mine inclined shaft and to make the consolidating material and falling rocks to form a completed surrounding rock with a self bearing capacity and eertain strength, The FLAC^3D was applied to make the numerical simulation for the backfilling and reinforcement plan. The simulation results showed that after the complex chemical backfilling and reinforcement, the vertical displacement was reduced by 85% and the backfilled strength reached 2 MPa which was higher than the surrounding rocks nearby. Thus the control results were obvious.
