The discharge pipe 6 is arranged in advance to the goaf, then the filling material is added into the stirring barrel 2, the filling slurry is obtained after the stirring component 3 is uniformly stirred, the filling slurry is conveyed to the discharge pipe 6 by the slurry pump 12, and the filling operation is carried out on the goaf.
As shown in fig. 4, a monitoring assembly 14 is provided in the discharge pipe 6 for monitoring the pressure of the filler slurry in the discharge pipe 6. As shown in fig. 4 to 6, the monitoring assembly 14 includes a protective case 1401 having a hollow interior, a top of the protective case 1401 being fixed to an inner wall of the discharge pipe 6, and a pressure sensor 1402 being fixed to an inner ceiling wall of the protective case 1401, a probe end of the pressure sensor 1402 being directed toward a bottom plate of the protective case 1401.
