摘要

Highwall or face profiling has long been used to facilitate the design and placement of front row blastholes to ensure optimum burdens. Traditionally, a large number of laser measurement points obtained from the rock face or highwall were input in profiling software packages. This method can be time consuming and requires access to the rock face with a complete view of the highwall to be successful. Stereo photography has also been used to generate the rock face surface, but this method also requires access to the highwall (and pit floor in some instances) for measurement of reference targets or points. With the advent of Unmanned Aerial Vehicles (UAV) and Small Unmanned Aircraft Systems (sUAS), a large section of the face or highwall can be quickly and accurately mapped using aerial photographs. The UAV/sUAS flies over the site taking numerous photographs on a pre-programmed grid spacing. The data from the photographs are then used to create a "point cloud" containing site-specific XYZ coordinate data. The point cloud data can then be used to generate individual face profiles, for optimum blast design. The data captured by the aerial reconnaissance can also be used to determine volumetric data, track volumetric changes over time, and provide "as drilled" coordinates of blastholes. This article describes techniques used to generate face profiles, blasthole collar placement, and blasthole drilling accuracy. It will demonstrate integration of new data gathering methods with traditional, blast design tools.
