摘　　要：阐述了压密注浆技术的原理及施工方案,介绍了压密注浆技术在田庄选煤厂土建施工中的应用情况,并分析了该技术在土建施工中为田庄选煤厂带来的经济效益。实践表明:压密注浆技术的使用,有效避免了在厂房内挖深基坑影响相关设备安全运行的情况,并大大提高了地基的承载力,消除了浅层回填土的不均匀沉降和不稳定问题。The paper described the principle and plan of the compact grouting technology, introduced the application of this technology in civil engineering construction at Tianzhuang coal preparation plant, and analyzed the benefit obtained by using this technology in Tianzhuang coal preparation. The construction practice show that by using the compact grouting technology, effectively avoided the effect of digging pit in the workshop on the safety running of equipment, and greatly improved the bearing capacity of foundation, solved the problems of uneven settlement of and unstable of backfill material.
