In order to improve the accuracy of coal reserve estimation in a certain coal mine,the ordinary Kriging method,inverse distance power method,and full coal seam modeling method were applied to numerically simulate ore bodies with complex shape characteristics,in order to improve their calculation accuracy.Comparing the resource reserves obtained by these three methods with the data in the original geological report,the results show that the error of the ordinary Kriging interpolation method in resource reserves is only 0.84%,which is much lower than the other two methods.It can be seen that the ordinary Kriging interpolation method has a high degree of agreement with the results of the original geological report,and can more accurately estimate resource reserves.
