摘　　要：针对煤矿总回风巷整修施工中,揭露陷落柱的二次冒顶区域堵塞主要通风断面的问题,金达煤矿采用预先搭设假顶防护网骨架的充填技术方案,利用充填、加固2种注浆材料的合理参数匹配和分区域、分地层使用的性能优势,实现了与特殊地质条件的完美匹配,发挥了注浆材料最佳使用效果。将大功率、高转速风动钻孔机具、特制注浆钻杆与超大排量、低压力风动注浆泵的联合应用,为一次成孔、大体积空洞区的快速充填施工提供了可靠保障,缩短充填工序时间。该技术为类似特殊地质条件下的冒顶区应急贯通施工提供了配套的注浆材料、钻孔及注浆设备和施工工艺等一整套技术保障体系。In view of the problem of exposing the secondary roof fall area of the collapse column and blocking the main ventilation section in the renovation construction of the total return airway of the coal mine,the filling technology scheme of pre-installing the skeleton of the false roof protection network was adopted in Jinda Mine.By using the reasonable parameter matching of the two grouting materials of filling and reinforcement and the performance advantages of sub-regional and sub-stratigraphic use,the perfect matching with special geological conditions was realized,and the best use effect of grouting materials was brought into play.The combined application of high-power,high-speed pneumatic drilling tools,special grouting drill pipes and super-large displacement,low-pressure pneumatic grouting pumps provided a reliable guarantee for the rapid filling construction of one-time hole-forming and large-volume cavity areas,and shortened the filling process time.It provided a complete set of technical support system of grouting materials,drilling and grouting equipment and construction technology for emergency cut-through construction of caving zone under similar special geological conditions.
