摘　　要：针对赵庄煤矿二号井2307工作面地表构筑物压煤问题,为提高煤炭资源回收率,应用覆岩离层注浆技术,通过减少覆岩离层量达到控制地表变形目的。依据现场条件合理确定采面覆岩离层注浆层位、注浆钻孔布置以及注浆参数,并进行工程应用。现场应用后,2307工作面开采影响区内地表得以较好控制,实现了构筑物压煤区域原煤安全回采,取得较好的经济及社会效益。In view of the pressed coal of surface structures at 2307 working face in No.2 Shaft of Zhaozhuang Colliery,the author proposes the application of separated strata grouting technology to control the surface deformation by reducing the overlying strata bed separation,including the grouting layer,grouting borehole layout and grouting parameters,whose field application results show it can control the surface in the mining affected zone and realize the safety coal mining.
