In order to resolve the treatment of inrush of high-pressure water and reinforcement in deep underground engineering, combined with the reinforcement mechanism research of chemical grouting material, not only the feasibility of a new type of chemical grout has been studied, but also the experimental research on properties of new types of chemical grout, such as mobility, penetrability, strength, anti-brushing performance, water genotoxicity and so on are performed in the laboratory; therefore the physicochemical characteristics of has been analyzed; the proper proportion of new chemical grout and its relative specifications have been given. In addition, based on a project case under water-inrush hazard, the field experiment has also been carried out; contrasted to other types of grout, such as cement with super fine slag, cement and water glass double grouts, and urea resin harnstoffharz, the applications and advantages of this chemical grout on inrush of high-pressure water controlling has further been proved. It is shown that this new chemical grout is quick reaction, high strength, well scouring resistance, innocuous and excellent performance of permeability and hydro-expansiveness. Ideal grouting effect has been reached for its good controllability and pumpability in the field test, contrasted to the styles of cement grouting material and some common chemical grout material, it has advantages of rapid transportation, convenient proportioning and simple technology; the conclusions obtained will devote to the following studies.
