Abstract: In order to solve the common problems like large quantities of work amount, long work project delay and secondary disaster during large channel water inrush plugging, the author invented a special drilling rig, textile capsule, developed and used quick-setting high strength grouting material and borehole-controlled grouting technology. 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.
