Abstract: After the climax of water conservancy and hydropower construction in China,the technical specifications of curtain grouting in hydraulic engineering have been quite mature.In recent years,with our country vigorously advocating the construction of green mines,the curtain grouting technology in mine has been developed.Many water rich mines in China have adopted curtain grouting technology to prevent and control water.However,the development of the curtain grouting technology is still relatively lagging behind,most of the technical standards are borrowed from curtain grouting in hydraulic engineering.In view of the above,combined with some problems encountered in curtain grouting design and construction,differences between curtain grouting the mine and in hydraulic engineering were analyzed from aspects of grouting purpose,Waterproof standards and grouting parameters (hole depth,pressure,section length,etc.).In addition some suggestions for curtain grouting in mine are put forward.Curtain grouting in mine are unique in the above aspects and should be improved and perfected in the specifications and procedures.
Key words: Curtain grouting,Mine water control,Waterproof standard,Differences
