Embodiment
[0039] This application belongs to the research field of blasting effect evaluation. The main technical achievements include the most common blast pile section Weibull distribution model research object of open-air step deep hole blasting, forming a geometric model for blast pile shape simulation;
[0040] A large number of blasting practices and related research results show that the pile shape conforming to the Weibull distribution is the main pile shape in the deep hole blasting of open steps. Weibull distribution curve, such as figure 1 shown;
[0041] A further study on the pile shape of Weibull distribution shows that the slope of the blast pile is approximately an inclined plane, and the top surface of the blast pile is approximately a paraboloid because of the blasting funnel section.

The present application discloses a three-dimensional simulation method for rock blocks on the surface of the explosive pile whose pile shape is Weibull distribution, including simplifying the pile shape of the Weibull distribution; simplifying the slope of the explosive pile into an inclined plane, and simplifying the parabola of the section into a V shape , the side of the explosive pile is simplified to a vertical plane; the heap geometric model of the Weibull distribution of the entire explosive pile is simplified to a pentagonal prism; it also includes steps 1‑13 of the overall algorithm steps of the three-dimensional simulation of the rock block on the surface of the explosive pile; The most common research object of the Weibull distribution model of the blast pile profile in hole blasting forms a geometric model for the simulation of the blast pile shape, and at the same time provides the overall algorithm steps for the three-dimensional simulation of the blast pile surface. This application can transform the blast pile into a two-dimensional Weibull distribution The model is transformed into a three-dimensional model; this application combines the pile shape of the blast pile and the block size of the rock block to form a three-dimensional model of the rock block on the surface of the blast pile; the three-dimensional model of the pile shape can be used to optimize the blasting parameters and improve the efficiency of the subsequent blasting process.
Description
technical field [0001] The present application relates to the technical field of blasting effect evaluation research, in particular to a three-dimensional simulation method for rock blocks on the surface of a blast pile whose pile shape is Weibull distribution. Background technique [0002] The blast pile shape parameters, block size distribution parameters and large block rate formed by deep hole blasting of open-air steps are important indicators to measure the blasting effect, which not only affect the blasting cost, but also have a direct impact on the cost of subsequent processes such as shoveling. For general blasting engineering, because the impact of blasting fragmentation on the whole production process is more obvious, there are many studies on the distribution of blasting fragmentation in blasting piles. However, with the increase of the difficulty of various earthworks and the increase of blasting costs, the shape of the blast pile in open-pit deep hole step blas...
