Publisher's Synopsis
Excerpt from Handbook of Rock Excavation, Methods and Cost
The reader will find an exceptionally large number of methods of excavating and transporting rock under different conditions in addition to a great many examples of actual costs given in detail. The tools and machines required for rock work have been described and illustrated in greater variety than hitherto. The six chapters devoted to drills and drilling alone would make a volume of considerable size. The chapters on cable and other well drills and on diamond and other core drills present more complete information on these subjects than can be found in 'any other book within my knowledge.
