Abstract
Drilling and blasting is the traditional method of shaft excavation. This is labor intensive and time consuming. With the advent of machine boring, the RBM, or raise-boring machine, was developed to increase safety and decrease the cost of shaft construction. Compared to conventional drill-and-blast shaft excavation methods, raise boring offers many advantages: (1) Safety; (2) increased productivity; (3) disturbance of the rock unit from its equilibrium state is not as great as when using drilling and blasting methods; (4) excavation crew size is smaller; and (5) resultant bottom-line reduction in cost of shaft construction.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
