Introduction of Vertical Mine Shaft Sinking by Full Section Boring Method

2012 
The shaft drilling method is a fully mechanized operated mine shaft sinking method when shaft sinking through the soft and weak overburden layer. the new full section boring method can reduce the number of reaming, the number of bits, energy consumption and increase completed advance rate of shaft over 20%, reduce emissions of waste drilling mud by 20% . The paper in detail stated the features of the Full Section boring method operation,the implementation mode,design principle and support technology.
