Embodiment Construction

[0053]The present invention will be described in further detail below according to the drawings and embodiments.

[0054] figure 1 For the flow chart of the method for automatic drawing of the exploration borehole deviation horizontal projection map of the present invention, refer to figure 1 , the present invention, the method for automatic drawing of exploration borehole deflection horizontal projection map, the steps include:

[0055] Step 1: Create an original data file. The information in the above original data file includes the opening coordinates of the exploration borehole, the number of measuring points, and the hole inclination parameters of each measuring point.

[0056] Step 2: Calculate the coordinates of each measuring point or the coordinates of each midpoint, and output the DXF format file for obtaining the horizontal projection map.

[0057] The coordinates of each measuring point are calculated by using the average zenith angle azimuth method, and the step...

Abstract

The invention discloses a method for automatically drawing a horizontal projection drawing for deflection of an exploration hole. The method comprises the steps that firstly, an original data file is established, wherein information of the original data file comprises hole opening coordinates of the exploration hole, the number of measuring points and hole deflection parameters of all the measuring points; secondly, coordinates of all the measuring points or coordinates of all midpoints are calculated, and an obtained DXF format file of the horizontal projection drawing is output; thirdly, a drawing tool is used for calling the DXF format file obtained in the second step, and the horizontal projection drawing is obtained. The method has the advantages of being simple in step, definite in concept and capable of avoiding the problems that in the manual drawing process, efficiency is low, and errors are likely to occur.

Description

technical field [0001] The invention relates to a method for automatically drawing a deflection horizontal projection map of an exploration borehole, which is mainly applied in the technical field of mineral exploration. Background technique [0002] Deflection of exploratory boreholes is a common phenomenon. Exploration drilling refers to a columnar hole with a small diameter and a large depth drilled underground by drilling equipment in geological exploration work; during the drilling process, due to geological, drilling technology and operation reasons, the The borehole bends, and deviates from the originally designed borehole zenith angle and azimuth angle. This phenomenon is called borehole deflection, or hole inclination for short. The deflection of exploratory boreholes is a common phenomenon, which should be paid attention to and studied. [0003] The horizontal projection map is one of the important ways to reflect the deviation of the borehole. To know whether t...
