In this article ,the current situation of the development of the technology of mining and filling in the course of the application of driftfill stoping method to the difficult orebody of mining in XiaoTieShan Mine is introduced which offers reference meaning to the production in similar mine

The entire-tails high-water solidified cemented fill is a kind of filling technique that is newly developed.

This paper introduced the present situation of filling techniques of mined-out areas adopted in China and foreign countries,summarizes the characteristics of traditional filling techniques adopted in mined-out areas,analyzes the status and the types of back filling methods in China,and looks forward to the application prospects of filling technique.

Test study of fly ash paste filling technology in Xingtai Mine;

Over the Past 30 years, Fankou Lead-Zinc Mine has made marked achievement in filling technology development.

A parametric method to design addendum surface for automotive panel;

The algorithm is suitable to generate additional surface such as the fill-hole surface,the smooth surface of the automotive panel contour,the addendum surface and so on.

Besides,the authors described how to fast and accurately create the addendum and blankholder as well,and take some examples to explain the validity of the assistant node scheme on making die-face.
