Optimization Study Of Opencast Mine Called Single-Mood Mining Area Based On Geostatistics

Based on the geostatistics to study the calculation of ore reserves and ore body delineation,geostatistical method has the incomparable advantages with other methods.Based on the geology and mining conditions,using the dependence of spatial data,simulating the data discreteness and volatility,partial linear interpolation can quantitatively estimate the reserves before mining,and can also maximize the local design of ore bodies.At present,the application of geostatistics has become a kind of tide.Combined with the computer and information provided by the exploration project,the calculation of the mine reserves can be initially realized.By proposing a slope angle at a reasonable depth,geostatistical method can provide a reasonable reference for mining and a series of optimal mining angles with different depths designed for a new undeveloped mine.The overall slope angle of mines will affect the delineation and optimization of mine realm and also directly affect the optimization of transportation system.Therefore,the research on slope angle is of great significanceBecause variables with spatial variability are generally difficult to measur.this method is particularly important to interpolate known points to predict unknown sampling points.In this paper,we compare three typical interpolation methods.In particular,the Kriging method is a method of interpolation based on the analysis of the correlation of variables.These three interpolation methods are compared in the system.This article mainly focuses on two aspects1.Calculation and analysis of slope stability and angle.Based on the method,six typical sections of the stope are taken,and the stability coefficients of the final and current slope are calculated respectively.Taking the divided Northwest as an example,we can analyze its impact on the stability coefficient by taking the value of different slope angle2.Open-pit iron ore body delineation and reserves calculation.Based on the borehole data and the spatial geologic status provided by the mining enterprises,this paper uses the section method to delineate the ore body after statistics of the grade and thickness data.In order to describe the three-dimensional shape of the ore body,the two-dimensional processed data is rasterized and the surface model of the ore body is superimposed to simulate the three-dimensional distribution of the orebody in the mineral resources evaluation system 1.0.Finally,according to the overall economic and technical indicators of the mining area and the relationship between industrial grade and reserves,the total reserves of iron ore in Gongchangling Dumu Mining Area are obtained using the formula of ore amount calculation.
