Latest Patents

Dayang Xuan holds a patent for an "Isolated overburden grouting filling method for coal gangue underground emission reduction." This method involves determining a grouting filling key stratum based on coal face information. It includes constructing a directional borehole from an underground tunnel to the grouting filling key stratum. Additionally, it features the construction of multiple branch holes downward in the main hole of the directional borehole. The method establishes a grouting filling system under the mine, where gangue obtained from excavation is made into a filling slurry. This slurry is then used to fill fractures below the key stratum, achieving harmless disposal of gangue while effectively supporting the key stratum and controlling surface subsidence.
