Abstract
An analysis method of drill hole quality comprises the steps of preparing reference hole verification data and hole site comparison data of an analyte, comparing and interpreting the reference hole verification data with the hole site comparison data, calculating a deviation value of each hole site of the hole site comparison data to the reference hole verification data, drawing a scatter diagram of X- and Y-axis coordinates of the hole sites in a 2D (two-dimensional) plane, and drawing a column diagram of the accumulated quantity of the hole sites perpendicular to the projection directions of the X- and Y-axis coordinates. The method can even integrate the scatter diagram of the X- and Y-axis coordinates and the column diagram, expressed in a Z-axis direction, of the accumulated quantity to display through a 3D (three-dimensional) graph, so that a user can distinguish the deviation and concentration of drill diameters of various tools more clearly, and the problem analysis and solving are facilitated.
