Abstract: Aiming at the problem of slow excavation speed and tense excavation connection caused by conventional construction
method of semi coal and rock roadway, this paper theoretically analyzed the stress state of coal and rock mass under blasting load.
Practical engineering application was carried out on the basis of reasonable selection of blasting parameters for rapid excavation of
semi coal and rock roadway. The results show that the engineering application effect is good, exceeding the expected monthly progress,
and creating conditions for ensuring the rapid excavation of semi coal and rock roadway and normal production continuity.

 Key words: semi coal and rock roadway; rapid excavation; blasting parameters; stress state
