Loading and Transportation in Tunnels
The types of transportation systems most suited to any tunnel are related to its length. If the tunnel is short, there is little need for manriding, and materials can be moved by hand or with the muck haulage equipment. A long tunnel will require some form of manrider, and special materials may need a dedicated carrier to avoid interruption of production or damage during transport. Cost and disruption factors have become increasingly important in recent years, and there has been a trend towards modular systems that provide a multi-function role. For instance, a locomotive can provide a manriding facility without interfering with its prime function as a haulage unit. Other, more complex, systems provide versatile and sophisticated cassette units that can be rapidly mounted on the prime mover. Also required for transport in tunnels are conveyors, hoists, cranes, loaders, carriers, locomotives and rolling stock, and all manner of railbound, monorail, and trackless equipment.
Increasingly sophisticated mucking machinery, which often involves high capital cost, is now common in tunnels. Techniques of muck handling have needed to keep pace with these developments in terms of speed, handling, capacity and reliability in order to control the cost of what is only a by-product of the tunnelling process. Much of the development work on underground muck handling has been carried out by the mining industry, whose production rates dwarf all but the largest civil tunnelling projects. Conveyors are increasingly used to transport spoil, not only in tunnels, but also in vertical shafts.

Alvenius Industrier AB
Quick Coupling Piping Systems
Alvenius Industrier of Sweden has for many years supplied piping systems to the tunnelling industry all over the world. Alvenius Tunnelling (AT) pipes with a diameter range between 48 mm and 508 mm are delivered either hot dip galvanised or untreated, and with the well known Alvenius quick coupling with self-sealing gasket. Alvenius has now expanded the product range with TP-pipes, a steel piping system which is thermo-plastic coated inside and outside. This combines the strength of steel and resistance of thermo-plastic to a wide variety of corrosive media. The TP-pipes are also ideal for applications where a very long service life is required, for instance in permanent fire fighting pipe systems. The Arlanda Link Consortium has installed Alvenius TP-pipes as fire fighting piping in 10 km of tunnels at the high speed railway between Stockholm City and Stockholm International Airport. Stockholm Transit Authority also chose the Alvenius TP-pipe system for fire hydrant pipes. The project planning for all fifty underground stations includes Alvenius TP-pipes in competition with stainless steel. SL chose the Alvenius pipe system because the quick coupling system makes installation simple and cost effective, as no welding is needed. TP-pipes are also frequently used in the mining industry as leaching, process and cooling water pipelines. Alvenius are planning for fast growing sales volume for TP-pipes, having invested in a new production line for thermo-pIastic coating of pipes and fittings.

Continental Conveyor Limited
Spoil and Muck Handling Systems
Continental provides an extensive range of muck haulage equipment for tunnelling applications. CCL's technology, knowledge and vast experience in the global mining sector has been applied, together with tunnelling specific technologies to bring the advantages of conveyor haulage to the
tunnelling industry.
Continental equipment can take the muck from a TBM (including the provision of the TBM tail section interface)and without interruption deliver to the surface and subsequently continue to transfer the material to the designated storage/loading point.
CCL's capability covers the supply of tail sections, heavy duty conveyor components, curving conveyor sections, belt storage allowing the conveyor to extend with the TBM, booster drives that allow for uninterrupted single flights that can be miles in length and vertical haulage systems. In addition Continental provides the on site know how and back-up that makes the entire system operate smoothly and efficiently.
Presently working on the Alptransit Tunnel Project in Switzerland, the ART Heathrow Project and the CTRL Project in London, it reflects Continental's capability and total awareness in today's modern, safe tunnelling environment.

Fenner Conveyor Belting
Heavyweight Conveyor Beltings
Fenner Conveyor Belting are exhibiting their extensive range of conveyor beltings, engineered to suit individual applications. The company is a global player supplying the entire spectrum of heavyweight conveyor beltings, including solid-woven, rubber ply and steel cord to the world's quarrying and bulk handling industries. With manufacturing facilities in United Kingdom, USA, Canada, South Africa, Australia and China, no other company can compete with this global coverage and the range of conveyor beltings produced. State-of-the art design, manufacturing and testing facilities ensure that Fenner can supply conveyor beltings suitable for a vast range of applications, manufactured to meet the most stringent international standards of safety, quality and durability.
Fenner recently introduced High Visibility (Hi-Vis) yellow covered Fenaplast belting into various markets, improving the safety and inspection capabilities, particularly on underground conveyors. The enhanced visibility of the yellow covers significantly improves the sighting of the conveyor's moving parts and structure against the belt, allowing easier inspection and making the conveyor itself more conspicuous. Hi-Vis Fenaplast belting is a product innovation driven by the need for improved safety, and is especially advantageous on man-riding conveyors, making the belt edges and conveyor moving parts more obvious to the rider. Fenaplast belting is also available in a range of other colours, to assist in belt identification on conveyor systems.

Metro de Madrid
Public Transport Service
Next October, Metro de Madrid, S.A. will celebrate its 82nd anniversary by offering a public transport service that is increasing its network and number of stations, as well as its quality service. An underground metro that is ever safer, cleaner, and more efficient.
Metro network extensions have resulted in 56.31 km and 37 new stations being added during the period 1995-1999. Since then, a new objective has been set for the opening by 2003 of another 54 km and 26 new stations.
The expansion of the Madrid Metro network has been carried out at costs substantially below the levels internationally accepted as possible. The Regional Government Secretary of Public Works, Town Planning and Transport has fostered this growth, which will double the size of the 1994 network. In 2003 the needs of underground users will be catered for by 234 stations, 225 km of tunnel infrastructure, 1,600 carriages, and more than 5,000 employees in service.
