RTK line lofting and hole arranging construction method in open bench blasting

The invention relates to the technical field of open bench blasting construction, in particular to an RTK line lofting and hole arranging construction method in open bench blasting. The method comprises the following steps: firstly, determining the position and the arrangement direction of a first row of holes, arranging a first hole in the first row, measuring and collecting the coordinate of the first hole by using an RTK broken part, measuring and collecting any point by using the RTK broken part in the determined arrangement direction of the first row of holes, and then carrying out linear lofting by using RTK; a first collection point and a second collection point are selected from a straight line starting point and a straight line ending point respectively, the mileage, mileage increment, offset distance and offset distance direction of a first row of holes are set in online lofting according to the hole distance and the row distance, then the first row of holes are arranged according to an RTK handbook
