| Abstract: | For gob side packing,there are two systems;the wind power and the pump power,both injecting filling materials with anhydrite or concrete as agglomerates. A new technique,developed by the authors, is presented in this paper. The new technique involves gob side packing with ganguecement agglomerate mixture sent by a wind power system comprising an IV type of rotary spraying gun. In the paper,the application and superiority of the new technique in roadway re-tainment are included and possible improvements are proposed. |
