摘　　要：注浆是将某些能固化的浆液注入围岩的裂缝或孔隙中,通过浆液固化后的结石体来改善围岩物理力学性质的方法。注浆的目的是防渗、堵漏、加固等。随着技术的发展,注浆技术从最初的井壁涌水注浆,到地面预注浆、井筒工作面预注浆等单一的注浆施工,发展到现在的井筒钻-注-凿平行、钻-注平行作业以及地面水平定向钻孔注浆等,根据注浆施工现场的具体情况往往采用的注浆材料也不同,常用的注浆材料有单液水泥浆、水泥-水玻璃双液浆、聚氨酯化学浆等。文章以麻家梁矿箕斗装载硐室注浆加固工程为例,介绍了不同的注浆材料及施工工艺,为类似注浆工程施工提供依据和参考。A grouting was to inject some grout to be consolidated into the cracks or pores of the surrounding rocks and after the grout consolidated,the solid bodies could improve the physical and mechanical properties of the surrounding rocks.The grouting purpose was to have a seepage prevention,leaking stoppage,reinforcement and others.With the technology development,the grouting technology was developed from an initial water inrush grouting of the mine shaft to a pregrouting at the surface,pregrouting at the working face in the mine shaft and the single grouting construction and to the present the drilling-grouting-sinking parallel operation in a mine shaft,a drilling-grouting parallel operation and surface horizontal hole grouting as well as others.According to the certain conditions of the grouting operation site,the grouting material applied were often different and the common grouting materials would be the single cement grout,cement-sodium silicate double liquid grouts,polyurethane chemical grout and others.Based on the grouting reinforcement engineering of the skip loading chamber in Majialiang Mine as an example,the different grouting materials and the construction technology were introduced and could provide the basis and references to the similar grouting engineering construction.
