Sandaozhuang Open-Pit Quality Block Modeling Based on Engineering Geological Profile

Article Preview

Abstract:

Block model is the precondition of open-pit mine optimization boundary design and mining design. In this paper, after studying the ore deposit model that using the optimization boundary, put forward to establish ore deposit quality block model based on the proposed Sandaozhuang engineering geological profile. Using prospecting line profile CAD drawings that obtained during the exploration phase, use two-dimensional coordinate conversion three-dimensional coordinates, the profile boundary curve smoothing, apply Delaunay triangulation and other technology to establish ore body contour model. Establish the ore body quality model based on the ore body contour model, use inverse distance weighted method in geostatistics for the assignment of ore body quality model, get the Sandaozhuang open pit quality block model. And based on this to estimate the reserves, lay the foundation for the follow work of the mine.
