Mining and tunnel construction Fluid Competence

In the mining and tunnel construction sector, engineers, technicians and workers battle against extremes: extreme pressure, extreme temperatures and extreme risks. The functionality of hydraulic installations is a kind of life insurance policy for the people working below ground, as critical safety systems rely on it. The two hydraulic system environments open and closed systems operate side-by-side in the field of mining. With CORSAVE for water-based systems and LUBESAVE MINING

How Tunnels Work HowStuffWorks

Tunnel Construction: Soft Ground and Hard Rock Workers generally use two basic techniques to advance a tunnel. In the full-face method, they excavate the entire diameter of the tunnel at the same time. This is most suitable for tunnels passing through strong ground or for building smaller tunnels.

Introduction Tunnel Basics Mining and Blasting

There are three broad categories of tunnels: mining, public works and transportation. Mine tunnels are used during ore extraction, enabling labourers or equipment to access mineral and metal deposits deep inside the earth. These tunnels are made using similar techniques as other types of

Tunnel construction: How to excavate the earth

Length and diameter of the tunnel. “For tunnels of more than 4.5 km and a regular section, a TBM is the most cost-efficient option”, he says. Layout and elevation of the tunnel. Numerous factors come into play here, such as the need to include auxiliary high capacity earth and rubble removal machinery (TBMs create a lot of waste material!), the diameter of the tunnel (complications could arise in tunnels with

Annex 13 Case study on tunnels European Commission

Tunnels constructed with TBM tend to be slightly higher in cost than those constructed with conventional construction methods. Nonetheless it has to be considered that the cost-efficiency of each construction method depends on the conditions of the ground as well as on project-design features. It is not deemed appropriate using the results of this assessment to compare different

27/07/2011 Some mining equipments such as road-headers and backhoes are commonly used for the tunnel excavation. The ground for excavation must be fully dry for applying the NATM and ground dewatering is also an essential process before the excavation. Another process relates to the ground modifications such as grouting and ground freezing is also common with this method in order to

How Tunnels Work HowStuffWorks

Tunnels built across the bottoms of rivers, bays and other bodies of water use the cut-and-cover method, which involves immersing a tube in a trench and covering it with material to keep the tube in place. Construction begins by dredging a trench in the riverbed or ocean floor. Long, prefabricated tube sections, made of steel or concrete and sealed to keep out water, are floated to the site and sunk in
