Zusammenfassung:	The invention discloses a method for tunnel smooth blasting drill construction. The method comprises the steps of installing a drilling rig direction controller on a rock drill, wherein the drilling rig direction controller is used for directly displaying up-and-down and left-right deflection directions of a drilling rig; before the rock drill enters a tunnel, performing line element section segmentation on a tunnel center line, calculating an azimuth of each section of tunnel center line according to the line element section, wherein the line element section comprises a straight line section, a straight easement section, an easement circular section, a circular curved section, a circular easement section and an easement straight section; the azimuth is an included angle alpha of each section of tunnel center line and the true north direction; after the rock drill enters the tunnel, setting the angle of the drilling rig direction controller as the angle alpha for each section of tunnel, causing a drilling rig
