PROBLEM TO BE SOLVED: To provide a blasting boring insertion angle control system high in versatility and reducible in cost while achieving the improvement of blasting efficiency and the reduction of outbreak by controlling a boring insertion angle with a small number of sensors. SOLUTION: The blasting boring insertion angle control system for use in carrying out boring using a boring machine 16 operated in parallel on a guide cell 18 supported to a boom 14 in a boring start point position set by a boring start point setting means, has horizontal angle detecting sensors 34, 36 mounted to the boom 14 to detect the horizontal angle of the boom 14 to thereby detect the horizontal angle of the guide cell 18, and a vertical angle detecting sensor 38 mounted to the boom 14 to detect the vertical angle of the guide cell 18 to thereby detect the vertical angle of the tip of the boring machine 16 operated in parallel on the guide cell 18. The boring insertion angle of the tip of the boring machine 16 on the guide cell 18 can be set based on the horizontal angle detected by the horizontal angle detecting sensors 34, 36 and on the vertical angle detected by the vertical angle detecting sensor 38.
