New Method of Hole-location in Bench Cut Blasting
Minghui Zhou · Blasting · 2007
The traditional method of hole-location in medium and deep hole blasting were according to engineer′s rough estimation for blasting region landform by eyenaked or with some simple measures, by this mean the parameters were made out and then adjusted in practice. It is difficult to precisely collect some important parameters such as bench height, bottom burden and actual burden of frontal line by rough estimation,so weak surface and larger burden would be caused and potential dangers would exist.The problem was well solved in haerwusu(哈尔乌素) project department by proposing a new method which combines the modern electronic surveying with blasting.
