(1)The purpose ofthe research topic:

1. To develop and improve my own engineering drawing design and the CADdrawing ability.

2. To learn how to solve problems efficiently with teamwork.

3. To able to use the knowledge learned in combination with the actualsituation to make up for the shortcoming of theoretical learning.

4. Also to master the methods, steps and the contents of mine design andcultivate the ability to have preliminary scientific research.

5. To improve the ability to write technical report using computerapplication

(2) Significance of the design topic

This graduationdesign can consolidate, deepen and expend the theoretical knowledge that I havelearned, and can connect what I learned in the series doing the mine visits. Itcan also establish a comprehensive system concept in the production process andsupplement the deficiencies of theoretical teaching and collect the relevantinformation for graduation design purpose. At the same time, graduation designis the most important part of our university curriculum.
