In order to meet the needs of new mining method and to enhance the qualities of stuff material filling physique

Primary mining method which is applied in mine of FuJia is the scraper goes out of the mine and glued fills the law.Along with the increasing of mining depth, the original problems that the mining method has originally appeared also the stop to reduce the mine efficiency and the enlarge of the loss dilution and the more heavier of labour intensity and the descend of the dressing technology quota. So the high layering used the scraper to go out the mine the gluedly fills the law. But the new method requires higher about filling the aspect intensity. Therefore after many ways of the experiments, the stuff material intensity improves greatly.
