stress field equation is established. By mass conservation equation of hydromechanics seepage flow field equation of coal bed gas
water and coal rock soild grain is established. These equations
secondary equations and fix solution condition form mathematical model of coal bed gas-water fluid soild coupling under stress. Using predigesting model to analyze single phase fluid soild coupling
distributing curve of pressure dynamic is obtained
effect of pressure distributing in coupling and non-coupling
so privide theory base for analysis of coal bed gas fluid solid coupling is analyzed.
