In order to solve the problem of strengthening the watery loose strata of roadway floor, the scheme of hydrophobic depressurization and then grouting water plugging and strengthening was adopted, the wall rock was reinforced by open grouting on the floor with grouting packer. The quick coagulation slurry of sodium silicate could successfully complete the water plugging and strengthening of the moving watery loose strata wall rock by intensive grouting drilling and the application of high ash water ratio cement.
