| Abstract: | A case study is made of the geological and mining conditions of Luling Coal Mine. Analyses are conducted through elastic theories and equivalence theories of the distribution of seam-floor abutment stresses. And a calculation method is developed as to the convergence of roadways in the floor strata of mining sections |

| Keywords: | mine ground pressure working face floor stress distributions roads displacements |
