Abstract: The paper summarized the technical experiences on the mining aspects of water environment protection of karst underground water in Xingtai Mining Ar ea. With the continued further study, great technical progress and achievements were obtained on the hydrogeological prediction, advance exploration, evaluation of th e coal minefield subregion, seam floor reconstruction, rapid construction of water resistance wall, construction of water sealing plug in sinkhole, stowing mining technol ogy and others. The mine advance detection and the safety adjustment before the mining operation was realized, the floor grouting reinforcement technology of the wat er pressurized mining in the down group seam, comprehensive grouting method and rapid construction of water resistance wall technology, construction of water sealin g plug technology in sinkhole, full mechanized stowing mining technology were applied to prevent the water inrush accident occurred in the coal mining face.
