Gui H.Venkat Reddy D.Sun L.2020-03-312020-03-312016International Journal of Earth Sciences and Engineering, 2016, Vol.9, 5, pp.1863-1868https://idr.nitk.ac.in/handle/123456789/13856The complex hydrogeological conditions in China coalmines have created a number of inherent water hazards. In the over 60 years of efforts in water hazards control, rich experiences have been accumulated in technology engineering. This article focuses on the major development stages and illustrates current applications of the key technologies in hydrological drilling, grouting and water plugging, and geophysical and geochemical prospecting, as well as the direction for future development, which can provide reference and facilitate communications with coalmines under similar conditions across the world. © 2016 CAFET-INNOVA TECHNICAL SOCIETY.
