The coupling mathematical model of coal and gas in the face of driving coal seam was set up, numerical simulation method was used to simulate the gas flow law under the action of blasting vibration on the working face. The simulation results showed that in the blasting and excavation process, due to the disturbance of the blast wave, significant fluctuations in the displacement and stress magnitude of each detection point appears, and the maximum displacement and stress were related to the distance from the working surface. The closer to the working surface, the greater the peak value of the displacement and stress, and the greater the influence of the blasting pulse on the coal and rock. However, when the coupled and uncoupled conditions were analyzed at the same point, the changes in the displacement and stress of the coal are smaller, it showed that the blasting action was the main factor that changes the physical and mechanical properties of the coal rock during the blasting process.
