In 1-D experiment, we found that without controlling the air outflow the water inflow rate was reduced compared with the water inflow rate under the condition, as observed by other researchers.

The results of the gas outburst simulation experiments showed that there was no difference in an air-flow reverse phenomenon in air inflow roadway between the upward ventilation and downward ventilation when the seam angle is ranging from 0 to 32 °.
