Establishment of a 3D solid model blasting rock mass based on intelligent lithology identification

With the development and application of intelligent drilling machine, the lithology data of blasting borehole can be obtained accurately. The blast-hole database is established to store and manage the intelligently identified blast-hole data. Taking the rock property data of blast hole as the sample, the inverse distance square method is used to interpolate the solid elements within the blasting area to generate the 3D solid model of blasting rock mass. The 3D solid model of rock mass was cut by using the polygon of blasting area and the triangular network of bench, and then the 3D solid model of blasting rock mass was obtained. C++ programming is used to realize all the process of establishing 3D solid model of blasting rock mass. Taking 918 bench blasting of an open pit mine in Xilinhot, Inner Mongolia as an example, the 3D solid model of rock mass in the blasting area is established. The blasting charge calculated by the three-dimensional rock mass model in this area is compared with that calculated by the single hole rock property. The results show that the blasting cost is effectively reduced and the blasting efficiency is improved by calculating the blasting charge by the three-dimensional rock mass model.
