In the last decade, great strides have been made in the raise boring technique in China. Extensively, the drilling and blasting method has been replaced by the mechanized raising method since 1980. There are now over 3C raise drills operating in more than 20 mines. The diameters for shaft boring varies from 500mm to 2000mm, and to depths up to 90m._x000D_
Tlis paper mainly describes the performance, mtLin technical achievments and applications of all four kinds of raise drills, and auxiliary equipment. Finally, some recommend- ations for future improvement in the raise boring technique are presented also.
