Abstract: The floor water inrush of working face seriously affects the safety production of coal mines. Taking 90101 working face
of Xinyugou Coal Mine as the engineering background, aiming at the problem of water inrush from the floor during the trial mining
stage, the water source of which Ordovician water, this paper analyzed the causes of water inrush combined with the geological
conditions, judged the water inrush channel, and determined that the water diversion channel was a fractured channel to communicate
with Ordovician limestone aquifer. By using clay cement slurry, the grouting water plugging process under high-pressure
dynamic water conditions was used in the water plugging treatment, and formulated the grouting water plugging scheme design.
The practice showed that the treatment effect was good, the water inflow of working face was reduced to 80 m³/h, the water plugging
rate was reduced to 87%, and the expected design goal was achieved.

Key words: floor water inrush; water diversion channel; clay cement slurry
