| Abstract: | Using the finite element method, this paper studies the stress distribution and fracture of surrounding rock of entries, especiallg the entry, floors, under the effect of gravity stress and coal mining. The reasons and affecting factors of floor heaving in Liziya Coal Mine are diocovered provides a basis for formulating controlling measures of floor heaving of the mine, the research also has directive signitiecnce for solving the floor heaving problem in other coal mines. |
