The intensity of gas flow and shockwave will attenuate at straight roadway, which decays more slowly earlierly, and attenuates faster in the late.
冲击气流强度在断面不变的直巷道中传播会发生衰减，前期超压衰减较为缓慢，后期超压衰减增快。

Lastly, experimental system for outburst shockwave was constructed; shockwave propagation at straight roadway was studied by the experimental research.
