| Abstract:In order to solve the water disasters caused by freezing holes of full-depth bedrock frozen shaft in western China, analysis was made on the form of annular water-transmitting channels in freezing holes and the in-rushing water mechanism with the case of water disasters control project of Hujiahe coal mine. The paper presents an innovating counter-flow water diversion grouting sealing technology and introduced its principle and construction process. The project practice proved that this technology can effectively and quickly control the in-rushing water disaster of freezing hole. |
