Raumatakseen

Raumatakseen is an excavation method used in various industries, primarily in the extractive and heavy construction sectors. It involves the sequential excavation of horizontal layers of soil, ore, or rock, often within a narrow trench or pit.

The process of Raumatakseen typically begins with the removal of surface material, followed by the creation of a narrow trench or shaft. From this point, the excavation proceeds in a series of horizontal layers, with each subsequent layer created by removing and carrying away excess material. This method is often favored for its efficient removal of horizontal sections of material, allowing for deeper and wider excavations with minimal effort.

Raumatakseen has been employed in the extraction of various minerals, such as coal, iron ore, and gold, as well as in the construction of tunnels and canals. The method is widely used in areas with limited access for transportation or where geographic conditions make traditional excavation methods impractical.

Advantages of Raumatakseen include increased efficiency in material removal, reduced energy consumption, and reduced environmental impact compared to traditional methods. However, it also presents potential drawbacks, including increased risk of collapse due to the removal of material in thin layers, as well as the need for specialized equipment to manage excavation materials.

The use of Raumatakseen has been documented across various regions, including South America, Asia, and Eastern Europe. Difficulties in excavating layered materials have led to exploration of alternative methods, including the employment of roller-compacted concrete and advanced tunnel boring machines.
