Intelligent design method for open-bench blasting

Abstract

The invention provides an intelligent design method for open-bench blasting. The intelligent design method comprises the steps of a 3D terrain point cloud accurate model of a blasting area is built; blastholes are subjected to self-adaptive arrangement; the blasthole depth is automatically calculated; single-blasthole charge calculation is conducted based on a VORONOI body; the blocked length is calculated automatically; and the blasthole arrangement result is visualized, and the coordinate, the depth, the charge amount and the filling length of each blasthole are displayed in a table form. The intelligent design method acquires great improvement on the aspects of bench blasting design precision, efficiency, economic benefits and the like and meets the requirements of bench blasting for fastness, accuracy and high efficiency.

Description

technical field [0001] The invention relates to the field of engineering blasting, in particular to an intelligent design method for open-air step blasting. Background technique [0002] The traditional blasting design only provides guidance and explanatory documents, and the blasting parameters are mostly determined by the designer with years of design experience, and the design itself lacks science and rationality. In addition, the on-site operators can only use the blasting design documents as a reference, and determine the minimum resistance line, coordinates, charge amount, packing length and other blasting parameters of each blast hole according to the site geology and terrain conditions, and rely on personal construction experience. Design and construction The empirically determined method has led to low efficiency, high economic cost, and poor safety of the blasting operation itself, and has further affected the efficiency of shoveling and excavation, and the overall...

Problems solved by technology

[0005] Since the existing blasting design system usually performs blasting design on the simplified ideal geometric model of the blasting area terrain, although the system can give the parameter value of each hole layout, due to the large deviation between the simplified terrain and the actual terrain, the rationality of the design parameters cannot be guaranteed. In particular, it cannot guarantee whether the minimum resistance line of the front row of holes meets the design requirements, which will affect the layout of the rear row of holes. Therefore, it is necessary to propose a new technical solution for improvement and perfection
