According to the study of the theory of the design and realization of the mine subsidence softward in this paper,which is the best development method; how to build topology; how to do spatial overlap analysis and how to draw the sectional view are explained deeply and clearly.

This paper was discussed some questions about distinguish,simplify drawings,noting in section which required in National Standard 4458.

But the section engine of the two-dimensional space can solve this problem.

In the process of using Kriging for analysis of Zijin Mine's reserves, the calculation of reserves profile is one of important charts.

The vertical profile is an important way to show actual wellbore trajectory.

Engineering geology histograms and profiles are basic plot in the engineering geology report.

Studying of the method on automatic producing the mining engineering profile chart by computer;

This paper talk about SOUTH CASS and MAPGIS,which how to use prospect line to survey coordinates production data and exactly make digitization profile chart.

The Discussion for the Relationship between the Data on profile map and Pre-Summer Flood Period Precipitation;

During the playback of the data obtained,curves of pressure-time, temperature-time and depth-time are matched by using time as a transverse coordinate to generate profile maps of pressure-depth and temperature-depth, which directly and accurately reflects the well bore pressure and temperature changing with well depth.

This paper discusses the necessary that measurement marking, sectionalview,sectional drawing,and profile standards in water conservancy and hydropower engineering drawings identify to those in architectural ones.

Finally,the use of DEM in a real engineering project is explained,including drawing the sectional drawing,computing the easy cubic mete of the earth,the statistics of surface area in slope,drawing the gird map of three dimensions and computing the surface area,with the paper mainly introducing the drawing of the grid map of three dimensions .

In this paper,the status quo of the vectorization of geological section drawings and the existing problems based on computer technology are analyzed first,and a new idea for the vectoriaztion of coal mine geological section drawings is put forth: firstly all kinds of lithological symbols are deleted,and then the boundary lines are reserved.
