| Abstract: | On the basis of detailed analysis on hydro-geological conditions of Huoluowan Coal Mine,a numerical model was set up according to the rock mechanical property and parameters of different overburden rock strata,numerical study was made on the destruction of the overburden roof in the extraction process of No.22101 face of the mine by using RFPA2D software of fluid-solid coupling analysis,and finally the whole process of roof from deformation to destruction and the destruction law were obtained. |
