The Geological Modeling And Calculation Of Mineral Reserves On Canzhuang Gold Deposit,Qilishan Mining Area

With the popularity of computer in mine production,the application of mining software is more and more,and the method of reserve calculation in geostatistics has also been accepted by most of the geological workers.While traditional segment method is gradually replaced by other reserves calculation method due to its large amount of calculation,time-consuming,low precision and other shortages.This paper takes the data of Canzhuang gold deposit in Qilishan mining area as an example,using 3DMine Mining Software which is a 3D platform to integrate and analysis the original geological data.Then the distance power inverse method of geostatistics is used to estimate the reserves of this gold deposit and compare with the traditional segment method,I get the following points:1.This paper established the drilling hole data and the surface model of Qilishan mining area,as while as the solid model,the block model and the grade model of the NO.?-1 ore body by using 3DMine mining software.2.Use the distance power inverse method of geostatistics to estimate the reserves of the block model and calculate the average grade and average thickness.The results show that the average thickness of each block of NO.?-1 ore body in Qilishan mining area is very small,and all of them are less than 2 meters.It means that the ore body is very thin,but the variation of thickness is homogeneous.The average grade of each block is about 3g/t,and the variation of grade is homogeneous.3.Distance power inverse method is used to estimate the reserves of NO.?-1 ore body.Then use the results to compare with the traditional segment method.It shows that the results of the two algorithms are similar and the errors are within the allowable range,especially the 332 segment.But distance power inverse method can shorten the calculation time greatly.To a certain extent,it can improve the production efficiency.
