This paper introduces the application of medium-length hole loose blasting with millisecond delay in subway excavation.Based on the practice,and through a series of tests to adjusting,the blasting parameters were reasonably selected.We summed up the very practical method to ensure the construction safety and speed up the work progress,and win valuable time for advance completing the entire subway.After many rounds of blasting,road and traffic and nearby units are not affected and absolutely safe.
