There should be an accurate survey map. When the distance between two working faces is15m, notice should be given first, and only one working face is allowed to advance, and people should be sent to guard at the places leading to the working face on both sides, and detonation can only be carried out after both sides evacuate to a safe place. After completion, the blasting time between the two measured excavation faces should be coordinated.
