Dismantling line
As degradation route is known in mining a horizontal underground workings in the deposit , which the mining area accompanied. In hard coal mining, mining routes are also referred to as seam routes.
Usage, history and size
Extraction routes are used for conveying , driving and ventilating the mining operations. The deposit is subdivided into subsections that are suitable for the respective mining method by means of mining stretches . In ore mining, mining routes are initially used to examine the deposit. In hard coal mining, mining routes within a construction site are usually only used once for a construction height . Under certain conditions, such as stable seam side rock and well-preserved route expansion , mining routes are also used twice. In the case of plate-shaped deposits, such as seams or tunnels , the mining stretches in the deposit usually run in strike direction. In the case of lenticular or other large-scale deposits, the mining stretches can also be aligned with cross cuts if necessary. The degradation routes are either blind shafts from Aufhauen or brake mountains or directly from the base or platform of ascended . Depending on the mining branch, the extent of the mining routes and their share in the overall route network is very different. In Western European hard coal mining , the proportion of mining routes in the overall route network is generally low. In the steep storage , the total length of the mining sections is greater than in the flat storage, with the same conveyance. In Ganger ore mining, the total length of the mining routes is usually greater than the other routes.
Further subdivision
In coal mining, the degradation routes, depending on the location of the longwall , divided into headgate and tailgate. The miner also calls mining routes that are used to extract mineral resources , coal removal route or belt route. If backfill mountains are transported over the mining routes, they are also called recovery routes. If the mining stretches are driven together with the longwall, they are called mining support stretches. Depending on the position of the excavation face in relation to the face, the miner differentiates between followed, driven ahead or driven excavation. In the case of traced or traced mining routes , the coal is mined and removed by the longwall workers, the adjacent rock is torn down by the local workers. In the case of excavated or advanced excavation sections, the face in front of the excavation front and in the case of concurrent excavation sections is almost at the same height as the excavation front. Dismantling routes that are used during dismantling are called dismantling routes. Mining sections that serve to investigate the deposit are called investigation sections.
