Abstract：
Aiming at the detecting of key factors to control tunnel overbreak and underbreak and evaluation of blasting effect, a drillhole detecting rod is developed, and the APP and B/S version information management platforms for tunnel overbreak and underbreak are developed. Connecting drillhole detecting rod with total station by means of the APP, the information of blasting hole 3D angle, position and tunnel profile after blasting are detected,calculated and transmitted, realizing detecting of blasting process and effect evaluation of blasting profile and providing reference for the following adjustment of blasting parameters and control of tunnel overbreak and underbreak.
