| Abstract: | The comprehensive test research including the field investigation of the rock masses structure and the laboratory testing of the rock and the discontinuity, the mechanical parameter estimation of the rock masses, and the network simulation of the discontinuity, for the rock formation in Yangjiaping coal mining worked out area has been carried out. The mechanical parameters of rock and discontinuity can be got base on the analysis of the test result. Then the mechanical parameters of rock masses can be estimated by Hoek-Brown method. The mechanical parameters of all the rock masses which involved in finite element calculation have been put forward associating with the geological condition. The FEM result proves that the mechanical parameters of rock masses is reasonable. |
