摘要
文中提出了测量控制下注浆减沉方法,优化了传统的注浆减沉方法,提高了减沉效果和煤炭采出率,节约了注浆成本,为指导“三下”开采实践和解决“三区”(煤采区、基岩区、地表下沉区)问题提供了依据。
In this paper,the method of grouting to reduce settlement was proposed under the surveying control,the traditional grouting method to reduce settlement was optimized,the effect of subsidence reduction and the coal recovery rate were improved,and the grouting cost was saved,and it provided the basis for guiding the"Three-under"mining practice and solving the problems of"Three areas"(coal mining area,bedrock area,and ground subsidence area).
