Rock Mass Quality Prediction of Open-Pit Gold Mine Slope Based on the Kriging Interpolation Method
https://orcid.org/0000-0002-8908-3038
Abstract Rock quality index (RQD) is a parameter which reflects the degree of rock fragmentation and is an important index for evaluating the stability and properties of rock masses in the field. Taking Chang Shanhao open pit gold mine in Inner Mongolia as the research object, RQD data from geological exploration drill core from the southwest stope are analyzed using the indicator Kriging interpolation method, which are then used as the sample points for variogram fitting in order to simulate the spatial variability of rock mass quality. Based on the geostatistics simulation prediction, the rock quality of the stope is predicted via interpolation, and a three-dimensional model corresponding to the RQD percentage and the risk of the slope rock mass is established to predict the quality of the slope rock mass of the stope, and a three-dimensional rock mass quality prediction diagram is constructed. Results show that the potential landslide area in the three-dimensional rock mass quality prediction map is consistent with field data and is consistent with the landslide disaster area revealed by excavations.
