Effective Filling Rate in Filling Mining’s Influence on Overlying Strata’s Movement
Advanced Materials Research, 2013Similarities and differences of overlying strata movement rule and abutment pressure distribution between filling stope and traditional strope was analysied guided by “practical mine pressure control theory ”. The admissible condition of strata’s depending from bending failure to caving was put forward, and caving zone’s height was analysied on the ...

Movement and deformation laws of the overlying strata in paste filling stope
Mining Science and Technology (China), 2011Abstract We combined the similar simulation with numerical simulation to analyze the movement and deformation features of overlying strata caused by paste backfill mining, study the movement and deformation laws of the overlying strata in paste backfill mining, structural movement of the stope strata as well as the stope stress distribution laws ...
