Book Description
This report describes the equipment, methods, and costs that are considered applicable for underground emplacement construction of nuclear explosives such as would be used in nuclear excavation. The test of the report discusses the available methods and techniques currently being used in 'big hole' (30-inch diameter and larger) drilling, tunneling, and conventional shafting. The technical data have been collected from the available literature as well as by personal contacts with the Government agencies and private industries concerned. (Author).

Book Description
The report describes the equipment, methods, and costs that are considered feasible for constructing underground emplacements for nuclear explosives such as would be used in nuclear excavation. The text of the report discusses the available methods and techniques currently being used in 'big hole' (36-inch diameter and larger) drilling, tunneling, and conventional shafting. The technical data have been collected from the available literature as well as by personal contacts with the Government agencies and private industries concerned. Big hole drilling methods can be divided into four types: churn drilling, auger drilling, calyx drilling, and rotary drilling. Of these, auger drilling is the most economical for holes to depths of 150 feet in soft material, and rotary drilling is by far the most popular choice for depths in excess of 150 feet. Discussions concerning mining and shafting cover the conventional cyclic method of drilling and blasting as well as the mechanical mining methods, which in the past few years have gained considerable popularity. Cost analyses for big hole drilling are included in Appendix A and analyses for tunneling and shafting are included in Appendix B.
