摘要
对高速公路下采空区充填注浆材料的选取进行了阐述,并通过对注浆材料浆液进行配比试验和分析,得出注浆材料的特性,指出煤矿采空区注浆浆液配合比应按帷幕孔、注浆孔的性质和孔内空洞、裂隙发育情况来确定。
The author gets description on selection of filling grouting material in the goaf under expressway,and according to get mixing ratio experiment and analysis on the grouting material slurry,gets the grouting material characteristics,points out that the grouting slurry mixing ratio of the coal mine goaf should be confirmed according to performance of curtain hole and grouting hole,inanition in hole,as well as crack development situation.
