The Study of Damaged Fields Evolutionary Law in Deep Mining of Coal with Filling
With the increase of mining depth, the coal seam gas-bearing capacity is often continuously increases. Therefore, there are great important significant to study the evolution law of the broken structures in coal and rock mass with gas on the condition of mining. In this paper, considering mechanics model coupled of tensile strains and compressive strain and the corresponding constitutive equations, the elastic-plastic finite element programs was secondary developed. The evolutionary law of volume strains and the damaged fields in rock mass can be obtained with the continued pushing of the coal working face, which provided theoretic references for the simultaneous production of coal and gas.
