Abstract: An isolated overburden grouting filling method for coal gangue underground emission reduction includes determining a grouting filling key stratum according to information of a coal face; constructing a directional borehole from an underground tunnel to the inside of the grouting filling key stratum; constructing a plurality of branch holes downward in a main hole of the directional borehole; and by establishing a grouting filling system under a mine, gangue obtained from excavation gangue of the mine and gangue sorting being made into a filling slurry by means of breaking and grinding, and the filling slurry filling fractures below the key stratum through the directional borehole. The gangue generated from a mine is directly made into a filling slurry under the mine and then fills overburden mining-induced fractures, thereby achieving harmless disposal of the gangue, effectively supporting a key stratum, and controlling stratum movement and surface subsidence.

Abstract: A high-frequency composite impactor including a high-frequency axial and a torsional impact assembly is disclosed. The high-frequency axial impact assembly includes an upper self-excited oscillation cavity, a lower self-excited oscillation cavity, an adjustment block and a lock nut. The torsional impact assembly includes an upper end cover, a reversing switch, a pendulum, a lower shell, a lower end cover, a nozzle, a connecting block and a retaining ring. The high-frequency axial impact assembly converts the flowing drilling fluid into a pulsed jet to achieve a high-frequency axial impact. The torsional impact assembly enables a torsional impact through a shunt, and finally enables a high-frequency composite impact, which can effectively reduce the stick-slip of the drill string, jump drilling and other downhole accidents. By reducing the friction between the drill string and the borehole wall, the impactor can reduce WOB loss, increase the ROP, and improve the drilling efficiency.
