| Abstract: | In order to control the surface subsidence during the mining of thin coal seam in Wangzhuang Coal Mine,this paper studies the control effect of pier pillar filling mining technology by means of physical simulation,test and engineering practice.The results show that the surface subsidence coefficient is 0.125 in the simulation test and 0.057 in Wangzhuang Coal Mine after the application of pier-column filling mining technology,which are less than the allowable value of the first-class damage of brick and concrete buildings.The technology of pillar filling effectively controls the surface subsidence of Wangzhuang Coal Mine. |
