[0002] During the coal mining process, a large number of goafs will be left behind. Coal filling can reduce the volume of the goafs and reduce the extent of surface subsidence, thereby alleviating damage to the surface environment. It can effectively support the roof, reduce surface subsidence and collapse, and thus realize the recycling of residual coal resources. This not only improves the recovery rate of coal resources, but also extends the service life of coal mines.
