PLEASE NOTE OVER SEAS BUYERS if the book extra large or heavy there. Rock Tunnels Three main types of primary support systems are presently used in rock tunnels in the United States. They are rock bolts, steel sets, and shotcrete. Shotcrete is a pneumatically applied large-aggregate concrete.

The need for a secondary lining in a tunnel supported by shotcrete depends on the purpose of the tunnel. Table 1 gives pres­. About this Book Catalog Record Details. Rock tunneling with steel supports, by Robert V. Proctor [and] Proctor, Robert V.

Tunnels and underground excavations, horizontal underground passageway produced by excavation or occasionally by nature’s action in dissolving a soluble rock, such as limestone.A vertical opening is usually called a s have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting.

and rock mechanics, several classification systems and so-called tunnelling methods were presented in different countries. A well-known example is Terzaghi's classification system for support of tunnels.

This descriptive system was developed in the U.S.A. and presented in a book with the title ”Rock Tunneling with Steel Supports” in The method of analysis used is that given by Commercial Shearing and Stamping Co. in its book, "Rock Tunneling With Steel Supports", by Proctor and White.

The input required is the radius of the rib, width of tunnel, assumed overbreak, assumed blocking point spacing, rock Author: P Kadnar. Engineering Classification of Rock Masses for the Design of Tunnel Support.

An analysis of some tunnel case records has revealed a useful correlation between the amount and type of permanent support and the rock mass qualityQ, with respect to tunnel numerical value ofQ ranges from (for exceptionally poor quality squeezing-ground) up to Cited by: Drill and blast is an excavation method used frequently in hard rock tunnelling because its flexibility allows for different layout setups.

WSP has used drill and blast to build tunnels with diameters up to 30m wide, mostly supported by steel bolts and. Tunneling through hard rock almost always involves blasting. Workers use a scaffold, called a jumbo, to place explosives quickly and safely.

The jumbo moves to the face of the tunnel, and drills mounted to the jumbo make several holes in the rock. The depth of the holes can vary depending on the type of rock, but a typical hole is about 10 feet. Publisher Summary. Terzaghi's proposed that the rock load factor (H p) is the height of the loosening zone over the tunnel roof, which is likely to load the steel hi's estimated these rock load factors from a m-wide steel-arch supported railroad tunnel in.

Modern rock tunnels are excavated by primarily two methods: Drill-and-Blast (D&B): It involves drilling charge holes advancing into rocks and using explosives to blast the rocks.

Tunnel Boring Machine (TBM): It involves cutting rock by a full face boring machines. Tunnelling machines for partial face (roadheader) are also used for rock excavation. Filed under: Tunneling.
