Abstract:

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 delete ed, and then the boundary lines are reserved. Finally the vectorization is achieved automatically.

Key words: （computer, vectorization, coal mine, section drawing）
