摘　　要：根据天马山硫金矿段中深孔(或深孔)爆破落矿后形成的采空区体积较大、且空区之间存在相互贯通、空区形态复杂的特点,提出整体密闭分段多点充填工艺,并结合采空区的实际情况,通过充填挡墙受力分析,确定挡墙结构及厚度。采用空区悬挂脱水管的方式加快空区脱水,同时对空区排出的水经过沉淀后经排水沟排往水仓。根据充填工艺特点制定充填跑浆预防方案及充填过程中相应的安全措施。实践应用证明此工艺适合于该类型空区,效果较为理想。According to the characteristics of Tianmashan S-Au Ore Block that there is a large cavity, interconnected empty areas, and complicated cavity shapes, this paper proposes an overall closed sectional multi-point filling technology, and determines the retaining wall structure and thickness through the force analysis of retaining wall and in accordance with the actual situation of the cavity area. The suspension dewatering tubes are set to accelerate the draining of water from the cavity area. Meanwhile, the water will be drained to the water sump along the drainage ditch after being precipitated. The filling slurry prevention programs and corresponding safety measures in the filling process are developed according to the characteristics of the filling technology. It is proved by practical application that this technology is suitable for this type of cavity area, and the effect is quite ideal.
