The Research Of Coal Mine Engineering Drawing System

The computer engineering drawing system is proved that can improve designing efficiency greatly,optimize designing scheme,decrease workers'pressure and inhence designing standard by a great deal of engineering practice. Moreover, it contributes greatly to economical and social information industry of our country .But the the computer engineering drawing technology is very poor in our coal mine,it can't effectly summarize mining designing experience and knowledge,and it can't resolve well a lot of questions about coal mine designing.So it is necessary to develope computer engineering drawing in order to satisfy the demand of security,high efficiency and low cost in production of mining.The thesis , for our country demand of information industry an d the trend of digital engineering drawing, chooses AutoCAD ---theplatform which is one-up in drawing and combine the C++ ,MF C, ACE and ObjectARX to research and delvelope coal mine engine ering drawing system. The structure , events handling,network, adva need,release and encrypt of coal mine engineering drawing system All these are very helpful to others who want to research coal min ing CAD.
