Abstract: Based on the actual situation that grouting reinforcement technique is widely applied in coal mine fractured surrounding rock, the research status of grouting technique is studied from the view of grouting material and theory, engineering technology and evaluation system. The problems of lagging theory study, grouting material existing lots of disadvantages, insufficient grouting equipment study, vacant grouting evaluation system existing and so on, have been pointed out in modern grouting technique, and according to that, the development direction of grouting technique is proposed.
