(1) Collection and input of graphic data Field or downhole measurement data can be recorded by electronic handbooks, portable devices and other equipment to be recorded and transmitted to the host. Manual recording can also be used, and the keyboard can be input to the host. Existing map data can be collected by a scanner or digitizer and input to the host. (2) Organization and processing of graphic data The amount of graphics data collected through the field or underground is quite large, and the data format has both geometric data, attribute data, and topological relationships. Therefore, through the organization and processing of graphic data, through encoding, coordinate calculation, and organization entity topology information, these geometric information, topology information, and attribute data are classified and stored according to a certain storage manner to form a basic information database. According to the characteristics and requirements of the mine map drawing, the existing legend can be formed into a legend library, and the basic elements of the mine road, the diverticulum, the wellbore, etc. can be formed into a pixel library, so as to facilitate the drawing method by using the pixel mosaic method. Speed ​​up the mapping. (3) Editing and generating graphics At present, most of the thematic drawing software at home and abroad is developed under the AUTOCAD environment. The mapping method can be divided into two types. The first is to map in the AUTOCAD environment, that is, to use external high-level language to form the readable files of AUTOCAD, then return to the AUTOCAD environment to map, or directly use AUTOCAD's internal language to program and generate graphics. The second is to directly generate the AUTOCAD graphic file while performing data processing in an external high-level language environment. (4) Dynamic modification of the mine map The mine map should be continuously modified and filled with the progress of the mine's mining activities to ensure its current status. Therefore, the mine map drawing system should have the function of modifying the data in the database at any time and modifying and filling the mine map in time. (5) Storage, display and output of mine maps In the drawing process of mine maps, the graphical data sources, graphic structure types and computer graphics process characteristics of various mine maps are different. Many mine maps have overlapping contents, and some mine maps can be derived or drawn from other mine maps. For example, the format of the map, the name of the map, the legend and the annotation of the coordinate grid are basically similar. The main roadway plan can be drawn from the plan of the mining project. The top and bottom maps can be topographic maps and mining by the mine field. The plan of the project was compiled. Therefore, different types of pixels can be stored in layers, and multiple patterns can be formed by inter-layer combination. At the same time, the mine map can be drawn on several basic drawings, and other drawings can be derived and edited from the basic drawings to reduce the amount of drawing work.

Computer aided drawing of mine map
The computer-aided drawing of the mine map is essentially based on the specific requirements of the mine map drawing. With the support of the computer database and the drawing software, a special mine map drawing system is developed to complete the automatic drawing process of the mine map. The computer mine mapping system should have the following basic functions:
