Abstract: Combined with single-row hole curtain grouting parameters selection and grouting construction results of zhongguan iron ore curtain grouting engineering, analysis and study were done by using unit permeable rate change curve, discreteness analysis, inspection hole testing result analysis and observation hole water level observation data. Study indicated: selection of single-row hole curtain grouting parameters and construction in mine curtain grouting were reasonable, and had a good grouting effects.

Key words: Single-row hole curtain grouting, Frequency curve, Discreteness
