摘要： Disclosed is a drill and blast method for advancing the tunnel face in a mine, which makes use of a mobile canopy. The mobile canopy having vertical supports connected to a frame that supports a shield. The mobile canopy allows for face production activities and ground support activities to occur simultaneously or near simultaneously. This allows for more rapid advancement of the tunnel face compared to traditional batch drill and blast techniques.
