The author provided a new idea of using special borehole-controlled drilling tools to put the textile capsule and applying the quick- setting high strength grouting material to plug the large channel of flowing water. A new grouting process, key technology and matching equipment for plugging water inrush channel have been achieved. By field application, this whole set of technology is highly efficient, reliable and economical. Key words: flowing water; water inrush through large channel; control of grouting; highly effective plugging technology
