Traffic infrastructure in mining areas (selected problems)

Abstract

The article discusses the issues of safety of operation of road and rail transport infrastructure objects in mining areas. In particular, the fol-lowing issues were discussed: the general characteristics of the mining deformations of the rock mass and the terrain surface, the impact of continuous and discontinuous deformations on the safety of the opera-tion of land transport infrastructure facilities and reinforcements of land transport infrastructure structures in mining areas. Examples of land transport structure reinforcements situated within the reach of mining influences are given.

Steel Relieving Constructions in Mining Areas as Temporary or Permanent Railway Bridges

“…As a result of mining exploitation, the area settles and mining hollows of subsidence are formedthe hollow adversely changes the geometry of the railway line (e.g. [1,2,6]). Practically in the entire area of mining subsidence hollow, the area is tilted by uneven settlement, which adversely affects the performance parameters of the track, e.g.…”

“…The railway embankment was widened and was strengthened with geo-synthetics on the sections, being within the range of the impact of the loads from structure supports (in April 2013). The use of synthetics geo-meshes and geogrids to reinforce embankments in mining area is an effective solution (e. g. [6]).…”
