Abstract
Rock grouting has been widely used in geotechnical and mining engineering. The grouts may be adhesives, chemical solutions, or have a variety of resinous origins. Penetrating, fracturing and compaction grouting have been studied by using theoretical analysis, experimental investigation, numerical simulation and in situ measurement. This chapter first presented a study of modeling grout propagation in transparent replica of rock fractures. Another modelling study on the chemical grout column permeated by water in transparent soil was also presented, which acts grouted barrier walls to reduce the permeability and/or strengthen the formation to prevent water inrush in the coal mining. Detailed experimental studies and finite element simulation are reported.
