The Cloud diagram simulating the wind pressure of the goaf. Figure 3 depicts the cloud diagram of the wind pressure of the simulated by using the CFD. The pressure on the side of the roadway of the air inlet reaches a maximum of 32.53 Pa when the initial wind speed occurs. Then, the lowest point of pressure reaches 1.12 Pa at the upper corner of the working face. Because the retaining roadway is directly connected to the goaf, the pressure difference between the roadways of the air inlet and the air return roadway would become larger.
